Features
■
Live-loaded, two-ferrule design.
■
Easy to install.
■
No torque is transmitted to tubing during installation.
■
Swagelok
®
gap inspection gauge ensures sufcient pull-up upon initial installation.
Two-Ferrule, Mechanical Grip Design
The two ferrules separate sealing and tube gripping
functions; each ferrule is optimized for its function.
The front ferrule creates a seal:
■
against the tting body
■
on the tubing outside diameter.
As the nut is turned, the back ferrule:
■
axially advances the front ferrule
■
radially applies an effective tube grip.
Advanced-Geometry, Hinging-Colleting
Back Ferrule Design
This design is standard on all 1/4 to 1 in. and 6 to
25 mm Swagelok stainless steel tube ttings to help
installers make more consistent, leak-tight tube
connections.
In these sizes, a patented case hardening process
and patented recessed and contoured geometry
provide a unique engineered advantage to the
Swagelok back ferrule, providing:
■
excellent gas-tight sealing and tube-gripping action
■
easily achieved proper installation
■
consistent remakes
■
excellent vibration fatigue resistance and tube
support
■
full compatibility with original Swagelok stainless
steel tube ttings of identical sizes.
Refer to 316 Stainless Steel Swagelok Tube Fittings
with Advanced Geometry Back Ferrules technical
report, MS-06-16, for additional information.

Fitting body
During assembly of the advanced-geometry design
(above), the front ferrule is driven into the fitting body and
the tubing to create primary seals, while the back ferrule
hinges inward to create a strong grip on the tubing. The
back ferrule geometry allows for an improved engineering
hinging-colleting™ action that translates axial motion into
radial swaging action on the tube, yet operates with a low
assembly torque requirement.

Messages from customers credit
Swagelok components and tube
ttings, along with Swagelok distributor
support, as having played a major role
in helping them succeed.
Swagelok continues to improve the
performance and reliability of the tube
tting for use in thousands of diverse
applications—including research,
alternative fuels, analytical and process
instrumentation, oil and gas, power,
petrochemical, and semiconductor
industries—and addressing such
critical issues as:
■
gas-tight seal
■
vibration (tube grip)
■
thermal shock
■
compliance with industry standards
■
installation
■
corrosion
■
intermix/interchange.
Gas-tight Seal
Excellent sealing and consistent
reassembly help ensure accurate
measurements of process
parameters—air, steam, fuel, and
water—to keep your plant operating
efciently. Moreover, Swagelok tube
ttings minimize fugitive emissions,
as well as process uid leakage and
operation costs.
Contact your authorized Swagelok sales
and service representative for more
information about Swagelok Energy
Emissions Surveys or to schedule a
survey.
Vibration (Tube Grip)
The patented case-hardening process
and back-ferrule geometry provide
excellent vibration fatigue resistance
and tube support—even in harsh
or stressful environments, such as
hydrocarbon processing, on-vehicle
applications, or rotary equipment
applications.
Swagelok has conducted vibration
tests, which show that the Swagelok
tube tting with advanced geometry
hinging-colleting back ferrule isolates
and protects the stress riser that is
generated along the tube during the
gripping part of assembly. The colleting
portion of the back ferrule allows
more material to contact the tube, for
additional support. This colleting action
enhances gripping performance and
provides both direct and axial support
to the gripping function. This design
minimizes the effects of bending
deection at the point of grip on the
tubing.
Contact your authorized Swagelok
representative for more information
about vibration test reports.
The Swagelok Tube Fitting Advantage
“Over 10 000 fittings
and not a single leak.”
“Used exclusively on our
equipment and has proven
to be very reliable and easy
to maintain.”
“
I have used Swagelok
fittings from when I was
a technician through
today in my role in facility
management. Would
recommend them for any
use.”

gas and subsea systems.
Swagelok has conducted tests in
accordance with ASTM B117-95 to
evaluate the corrosion resistance of
Swagelok tube ttings.
Contact your authorized Swagelok
representative for more information
about corrosion resistance test reports.
Intermix/Interchange
Swagelok recommends NO intermix/
interchange of Swagelok tube tting
components with other manufacturers’
components.
■
No industrial design standard
exists for two ferrule tube ttings.
Each company makes components
to its own design and not to any
recognized standards.
■
Interchanging and intermixing
tube tting components can result
in unpredictable performance,
environmental releases, increased
costs, and can be dangerous in
critical applications.
Thermal Shock
The elastic, live-loaded two-ferrule
design compensates for changes in
temperature during system start-up
and shutdown and helps eliminate
leakage related to rapid thermal
expansion or contraction.
Swagelok has conducted tests
that demonstrated the capability of
Swagelok tube ttings to withstand
thermal shock and high temperature.
Contact your authorized Swagelok
representative for more information
about thermal shock test reports.
Compliance with
Industry Standards
Swagelok Company works with
standards organizations around the
world to provide you with products that
address your needs.

■
To determine pressure ratings in accordance with ASME B31.1, Power Piping:
■
carbon steel material—multiply by 0.85.
Stainless steel and brass material ratings remain the same.
■
To determine MPa, multiply bar by 0.10.

Bored-Through Fittings for Thermocouples,
Dip Tubes, and Heat Exchanger Tees
Swagelok bored-through male connectors accommodate
thermocouples or dip tubes. Most male connectors are
available as a bored-through tting, but male connectors
whose pipe thread end is small relative to the tube tting
end—such as -600-1-2 or -8M0-1-2RT—cannot be bored
through.
Swagelok bored-through reducers and standard Swagelok
tees can be used to create a heat exchanger tee.
To order bored-through ttings, add BT to the ordering
number. Example: SS-400-1-4BT
Bored-through ttings have a reduced pressure rating.
In general, we have multiplied the allowable working
pressure of the tubing, as found on the Tubing Data Sheet,
MS-01-107, by the factors in the table to the right.
➀ The E dimension is the minimum nominal opening. These ttings may have
a larger opening at the pipe/straight thread end.

Vent Protectors
Mud Dauber
Swagelok vent protectors, more commonly
known as mud dauber ttings, protect open
ends of instruments, tubing, outlet vents, and
bleed-off lines.
The mesh wire screen prevents foreign objects,
such as mud dauber insects, from entering and
clogging various systems and causing damage.
Vent protectors are available in stainless steel
and brass. To order brass, replace SS in the
ordering number with B.

Solve Alignment Problems and Reduce Inventories
Swagelok tube adapters can help eliminate difcult alignment problems and
reduce inventories. Swagelok tube adapters can be used with any Swagelok tube
ttings in this catalog. So, stocking union elbows and union tees in various sizes
and materials—along with commonly used Swagelok adapters—eliminates the
need for stocking special elbows and tees.
Typical Alignment Problem
When installing pipe elbows or tees, it is often difcult to align the tting with the
desired run.
• Swagelok tube adapters are to be used ONLY in Swagelok tube ttings.
Use in ttings made by other manufacturers may result in leakage or
slippage.
Tube Adapters
-
BW
1. In this example, the
installation requires
connecting tubing to a
female end connection.
2. When the pipe connection
is tightened, the male elbow
points in the wrong direction
for the desired run. Loosening
the pipe connection could
mean leakage at the pipe
thread.
3. Tighten the pipe
connection of a
Swagelok male adapter
into the female end
connection.
4. Connect a Swagelok union
elbow or tee to the adapter by
tightening the Swagelok tube
tting with a wrench, while
holding the elbow or tee in the
desired direction. Insert the
tubing into the other end of the
Swagelok elbow or tee and
install the tting.
Swagelok Solution
By using a Swagelok tube adapter in conjunction with a union elbow or tee, these
difculties can be avoided.

Knurled Female
The Swagelok knurled nut tube tting provides a leak-tight seal without the
use of inserts on most wall thicknesses of polyethylene tubing. Inserts may be
required for larger sizes.
To set the ferrules on the tubing, initial connections must be made with a
wrench, tightening the nut one and one-quarter turns from nger-tight (three-
quarter turn for 1/16, 1/8 and 3/16 in.; 2, 3, and 4 mm ttings). Leak-tight
connections may be reassembled with nger-tight assembly.
To order a knurled nut, add K to the female nut basic ordering number.
Example: B-402-1K
To order a knurled nut on an assembled tting with nylon ferrules, add KN to
the tting ordering number.
Example: SS-400-1-2KN
To order a knurled nut on an assembled tting with PTFE ferrules, add KT to
the tting ordering number.

installer to quickly measure the gap between
the nut and the tting body with a standard
Swagelok gap gauge during initial installation.
The gaugeable preswage tool is distinguished
from the standard tool by the addition of a
colored band located between the wrench pad
and the Swagelok tube tting end.

Installation Instructions
Swagelok tube ttings 1 in./25 mm and smaller can be installed quickly, easily, and reliably with simple hand tools.
Over 1 in./25 mm sizes require use of a hydraulic swaging unit to swage the ferrules onto the tubing.
Safety Precautions
■
Do not bleed system by loosening tting nut or tting plug.
■
Do not assemble or tighten ttings when system is
pressurized.
■
Make sure that the tubing rests rmly on the shoulder of the
tube tting body before tightening the nut.
■
Use the correct Swagelok gap inspection gauge to ensure
sufcient pull-up upon initial installation.
■
Always use proper thread sealants on tapered pipe
threads.
■
Do not mix materials or tting components from various
manufacturers—tubing, ferrules, nuts, and tting bodies.
■
Never turn tting body. Instead, hold tting body and turn
nut.
■
Avoid unnecessary disassembly of unused ttings.
■
Use only long reducers in female Swagelok end
connections.
See the instructions starting on the next page for installation
of Swagelok tube ttings, O-seal male connectors, caps and
plugs, port connectors, tube adapters, positionable elbows and
tees, weld ttings, depth marking tool, and preswaging tool.
Tubing Considerations
■
Metal tubing material should be softer than tting material.
For example, stainless steel tubing should not be used with
brass ttings.
■
When tubing and ttings are made of the same material,
tubing must be fully annealed.
■
Always use an insert with extremely soft or pliable plastic
tubing.
■
Extremes of wall thickness should always be checked
against the suggested minimum and maximum wall
thickness limitations.
■
Surface nish is very important to proper sealing. Tubing
with any kind of depression, scratch, raised portion, or
other surface defect will be difcult to seal, particularly in
gas service.
■
Tubing that is oval and will not easily t through tting nuts,
ferrules, and bodies should never be forced into the tting.
Refer to Tubing Data catalog, MS-01-107, for additional
information about tubing selection.
Gaugeability
On initial installation, the Swagelok gap inspection gauge
assures the installer or inspector that a tting has been
sufciently tightened.
• Always depressurize a system before adjusting the
tightness of a tube tting connection.
Position the Swagelok gap inspection gauge next to the gap between the nut and body.
If the gauge will enter the gap,
additional tightening is required.
If the gauge will not enter the gap, the
tting is sufciently tightened.

Swagelok Tube Fittings Up to 1 in./25 mm
These instructions apply both to traditional ttings and to ttings with the advanced back-ferrule geometry.
Safe practices and proper installation are imperative to the performance of the Swagelok tube tting, especially in critical
applications.
For 5/8, 3/4, 7/8 and 1 in.; 16, 18, 20, 22 and 25 mm tube ttings, in all materials except for aluminum and brass, it is a best practice
to preswage the ferrules onto the tube using a Swagelok multihead hydraulic swaging unit (MHSU) to lower installation time and
increase ease of installation (see Multihead Hydraulic Swaging Unit (MHSU), Setup and Operating Instructions, MS-12-37).
Installation Instructions
Fully insert the tube into the tting and
against the shoulder; rotate the nut
nger-tight.
High-pressure applications and high
safety-factor systems: Further tighten
the nut until the tube will not turn by
hand or move axially in the fitting.
Mark the nut at the 6 o’clock position. While holding the tting body steady,
tighten the nut one and one-quarter
turns to the 9 o’clock position.
For 1/16, 1/8, and 3/16 in.; 2, 3, and
4 mm tube fittings, tighten the nut only
three-quarters turn to the 3 o’clock
position.
Swagelok Tube Fittings Over 1 in./25 mm
1. Preswage the ferrules onto the
tube using a Swagelok multihead
hydraulic swaging unit (MHSU).
2. Apply the lubricant packaged
with the tting lightly to the body
threads and the rear surface of the
back ferrule. For gas service also
apply lightly to the front angled
surface of the front ferrule.
3. Insert the tube with preswaged
ferrules into the tting until the
front ferrule seats against the tting
body; rotate the nut nger-tight.
4. Mark the nut at the 6 o’clock
position.
5. While holding the tting body
steady, tighten the nut one-half
turn to the 12 o’clock position.
Use the Swagelok MHSU gap
inspection gauge to ensure that the
fitting has been tightened sufficiently.
Reassembly—All Sizes
You may disassemble and reassemble Swagelok tube ttings many times.
• Always depressurize the system before disassembling a Swagelok tube tting.
Prior to disassembly, mark the tube at
the back of the nut; mark a line along
the nut and tting body ats.
Use these marks to ensure that you
return the nut to the previously pulled-
up position.
Insert the tube with preswaged ferrules
into the tting until the front ferrule
seats against the tting body.
Over 1 in./25 mm sizes: If needed,
reapply lubricant lightly to the body
threads and the rear surface of the
back ferrule.
While holding the tting body steady,
rotate the nut with a wrench to the
previously pulled-up position, as
indicated by the marks on the tube
and ats. At this point, you will feel
a signicant increase in resistance.
Tighten the nut slightly.
• Do not use the Swagelok gap inspection gauge with reassembled ttings.
O-Seal Male Connectors
1. Turn the O-seal connector into the female end until it is nger-tight.
2. Tighten the O-seal connector until it makes metal-to-metal contact with the
face of the female end.
3. Tighten slightly with a wrench.

Welding Precautions for Swagelok Tube Fittings with Weld End Connections
1. Remove the nut and ferrules.
2. Turn a Swagelok tube tting plug or another nut onto the
tting so that it is nger-tight. This protects the threads
and sealing components.
3. Provide a suitable heat sink to dissipate the heat.
4. Tack weld at four positions 90° apart to hold the tting in
place and to ensure alignment and concentricity of the
components.
5. Complete the weld.
6. Remove the plug or nut and replace the nut and ferrules.
• Caution: When welding carbon steel ttings, the heat
often removes the protective oil from the threads.
It is important to apply another lubricant, such as
Goop™ thread lubricant.
Depth Marking Tool
Fig. 2Fig. 1
1. Insert cleanly cut, fully deburred
tube into the depth marking tool
(DMT) until the tube is against the
shoulder of the tool. Using a pen
or pencil, mark the tube at the top
of the DMT (Fig. 1).
2. Remove the tube from the DMT
and insert it into the Swagelok
tting until it is against the shoulder
of the tting body (Fig. 2). Rotate
the nut nger-tight. If any portion of
the mark on the tube can be seen
above the tting nut, the tube is not
fully inserted into the tting.
3. While holding the tting body
steady, follow Swagelok tube
tting installation instructions,
page 70.
Fig. 1
Fig. 2
Fig. 3
NOTE: These instructions apply only to
non-gauageable preswaging tools. Tool

tool body and that the nut is nger-
tight.
4. Mark the nut at the 6 o’clock
position.
5. While holding the preswaging tool
steady, tighten the nut one and
one-quarter turns to the 9 o’clock
position.
For 1/16, 1/8, and 3/16 in.; 2, 3,
and 4 mm tube fittings, tighten the
nut only three-quarters turn to the
3 o’clock position (Fig. 1).
6. Loosen the nut.
7. Remove the tube with preswaged
ferrules from the preswaging tool.
If the tube sticks in the preswaging
tool, remove the tube by gently
rocking it back and forth. Do not
turn the tube (Fig. 2).
8. Insert the tube with preswaged
ferrules into the tting until the front
ferrule seats against the tting body.
9. While holding the tting body
steady, rotate the nut with a
wrench to the previously pulled-up
position; at this point, you will feel
a signicant increase in resistance.
