Swagelok supplies or sources, based on specific material properties, the following wide range of tubing options to meet a variety of application needs as a full solution provider:

Stainless Steel Tubing

Seamless stainless steel tubing in fractional, metric, and imperial sizes that is instrumentation grade, chemically cleaned and passivated to comply with ASTM G93 Level A and CGA 4.1, and thermocouple-cleaned to meet the cleanliness requirements of ASTM A632-S3, as well as welded stainless steel tubing in fractional sizes to be used with Swagelok components.

Ultrahigh-Purity (UHP) and High-Purity Stainless Steel Tubing

This tubing is ultrahigh-purity, coaxial, chemically cleaned and passivated, and thermocouple-cleaned 316L stainless steel available in size: 1/8 to 2 in and 6 to 18 mm. The tube ends are prepared for orbital welding.

304/304L Welded Tubing


Materials 304/304L and 316/316L stainless steel
Pressure Ratings Up to 8160 psig
Sizes 1/8 to 1 in. outside diameter
Markings Size, material, specification, and heat number

Cone and Thread Tubing—IPT Series

IPT series tubing is 316 stainless steel with working pressures up to 20 000 psig (1378 bar) for use with medium-pressure fittings, as well as high-pressure tubing rated up to 60 000 psig (4134 bar) for use in high-pressure applications.

Medium-Pressure Tubing—FK Series

316/316L 1/8-hard and heavy annealed tubing in lengths of 20 ft. and metric lengths up to 6 meters for use with Swagelok medium-pressure fittings as a complete solution. Cold-drawn 1/8-hard tubing has increased material strength which allows for reduced wall thickness and enhanced flow through the same diameter tube. All Swagelok medium-pressure tubing is marked to indicate size, material, condition, and heat number.

3/8 in. OD, 0.125 in. wall
9/16 in. OD, 0.187 in. wall

Jacketed Tubing and Insulated Tubing

Swagelok® jacketed tubing helps provide increased protection against galvanic and atmospheric corrosion. Swagelok insulated tubing is designed for use in applications such as steam supply, condensate return, and gas and liquid transport lines, where weatherproofing and energy conservation are important. Swagelok insulated tubing offers a cost-effective alternative to field-installed insulation of small-diameter tubing systems.

Jacketed, Pre-Insulated Tubing Bundles—Electric-Traced and Steam-Traced

Swagelok pre-insulated traced tubing bundles provide reliable process temperature maintenance in a variety of analytical and process instrumentation applications, including impulse lines, sample lines, and process lines and provide an economical choice compared to field tracing and insulating. The parallel configuration—process and tracer lines are parallel inside the bundle—allows all tubes to bend together in as little as an 8 in. (20.3 cm) radius in tubing sizes up to 3/4 in. or 12 mm, so the bundle is easier to route and connect in the field than cabled bundles.


Materials316 / 316L stainless steel, copper, or PFA with PVC or urethane jacket
Sizes1/4 to 3/4 in.; 6 to 12 mm
Pressure Ratings
Fractional TubingUp to 10 900 psig (751 bar)
Metric Tubing Up to 420 bar (6095 psig)
Maximum Process Temperature220°F (104°C)

Electric-Traced Tubing

Swagelok electric-traced bundled tubing maintains consistent temperatures in long, continuous lengths of impulse and sample lines for freeze protection, temperature maintenance up to 250°F (121°C), or viscosity control

Steam-Traced Tubing

Swagelok light steam-traced bundled tubing is typically used for freeze protection of instrument impulse lines and analyzer transport lines, maintaining temperatures in smaller diameter process lines from 50 to 200°F (10 to 93°C). Swagelok heavy steam-traced bundled tubing is typically used to maintain higher process temperature from 200 to 400°F (93 to 204°C) or for viscosity control. Applications can include impulse, sampling, and process lines.
