Gaugeable Tube Fittings and Adapter Fittings 2
Features
■ Live-loaded, two-ferrule design.
■ Easy to install.
■ No torque is transmitted to tubing during installation.
■ Swagelok® gap inspection gauge ensures sufficient 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 fitting 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 1/2 in. and 6
to 12 mm Swagelok stainless steel tube fittings 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 unique engineering to the Swagelok back
ferrule. The hinging-colleting back ferrule design
expands on the already robust performance of the
traditional ferrule design and provides:
■ 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 fittings of identical sizes.

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.

“Over 10 000 fittings
and not a single leak.”
That is the message one customer
wanted to share, crediting Swagelok
components and tube fittings
along with Swagelok distributor
support, as having played a major
role in completing—and obtaining
independent, third-party certification
for—two 12 000 ton oil rigs.
And that is part of the ongoing story
behind the continuous improvement
efforts that Swagelok has initiated and
sustained since the development and
patent of the original two-ferrule tube
fitting more than 50 years ago.
Today, as everyone is being called on
to “do more with less” and to recognize
value, Swagelok continues to improve
the leak-tight design of the tube
fitting for use in thousands of diverse
applications—including research,
analytical and process instrumentation,
bioprocessing, oil and gas, power,
petrochemical, and semiconductor
industries—and addressing such
critical issues as:
■ leakage
■ vibration (tube grip)
■ thermal shock
■ compliance with industry standards
■ installation
■ corrosion
■ intermix/interchange.
Leakage
Excellent gas-tight sealing and
consistent reassembly help ensure
accurate measurements of process
parameters—air, steam, fuel, and
water—to keep your plant operating
efficiently. Moreover, Swagelok tube
fittings minimize fugitive emissions,
as well as process fluid leakage and
operation costs.
From 1999 through 2004, more than
250 000 fittings in gas service at more
than 400 different process installations
were leak tested with Swagelok Snoop®
liquid leak detector. 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
fuel processing or rotary equipment
applications.
Swagelok has conducted rotary flex
tests, which show that the Swagelok
tube fitting 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 deflection at the
point of grip on the tubing.
Contact your authorized Swagelok
about vibration test reports.
The Swagelok Tube Fitting Advantage

Corrosion
Swagelok tube fittings are available
in a variety of materials, including
controlled-chemistry 316 stainless
steel and many other alloys for
enhanced corrosion resistance in a
variety of applications, including sour
gas and subsea systems.
Swagelok has conducted tests in
accordance with ASTM B117-95 to
evaluate the corrosion resistance of
Swagelok tube fittings.
about corrosion resistance test reports.
Intermix/Interchange
This practice can be dangerous.
Leak-tight seals that will withstand
high pressure, vibration, vacuum,
and temperature changes depend
on close tolerances and consistent,
exacting quality control in conjunction
with good design principles. The
critical interaction of precision parts is
essential for reliability and safety.
Components of other manufacturers
may look like Swagelok tube fitting
components—but they cannot be
manufactured in accordance with
Swagelok engineering standards, nor
do they benefit from innovations in
design and manufacture defined by 36
active Swagelok tube fitting patents
issued since 1989.
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 fittings to withstand
thermal shock and high temperature.

Pipe End (NPT and ISO 7)
Pressure Ratings Basis
Pressure ratings for fittings with both tube fitting and pipe
thread ends are determined by the end connection with the
lower pressure rating. The table lists pressure ratings for male
and female tapered pipe thread ends. For female and male
pipe threads to have the same pressure rating in the same
nominal pipe size, the female thread would require a heavier
wall, resulting in a fitting too large and bulky to be practical.
SAE/MS Fittings Pressure Ratings Basis
Pressure ratings are based on SAE J1926/3 at ambient
temperature.
Some fittings with AN, O-seal, and SAE/MS ends may have
lower ratings. For more information, contact your authorized
Swagelok representative.
Pressure Ratings
Swagelok Tube Fitting Pressure Ratings

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 fitting,
but male connectors whose pipe thread end is small
relative to the tube fitting 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 fittings, add BT to the ordering
number.
Example: SS-400-1-4BT
Bored-through fittings have a reduced pressure
rating. Contact your authorized Swagelok
representative for details.

Vent Protectors Mud Dauber
Swagelok vent protectors, more commonly
known as mud dauber fittings, 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.

Kwik-Clamp Flange To Swagelok Tube Fitting

Solve Alignment Problems and Reduce Inventories
Swagelok tube adapters can help eliminate difficult alignment problems and
reduce inventories. Swagelok tube adapters can be used with any Swagelok tube
fittings 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 difficult to align the fitting with the
desired run.
 Swagelok tube adapters are to be used ONLY in Swagelok tube fittings.
Use in fittings 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
fitting 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 fitting.
Swagelok Solution
By using a Swagelok tube adapter in conjunction with a union elbow or tee, these
difficulties can be avoided.
