Stainless Steel Tubing
Instrumentation-grade seamless stainless-steel tubing is available in fractional, metric, and imperial sizes. It is chemically cleaned and passivated to ASTM G93 Level A and CGA 4.1 standards and thermocouple-cleaned per ASTM A632-S3. Additionally, welded stainless steel tubing in fractional sizes can be used with Swagelok components.
Ultrahigh-Purity (UHP) and High-Purity Stainless Steel Tubing
Made from 316L stainless steel, this tubing undergoes rigorous chemical cleaning and passivation processes, as well as thermocouple cleaning, to achieve ultrahigh purity. Available in sizes ranging from 1/8 to 2 in and 6 to 18 mm, it is ideal for applications requiring exceptional cleanliness and corrosion resistance. Additionally, the tube ends are prepared for orbital welding, facilitating easy and reliable installation.

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.

| Sizes | 1/4 to 1/2 in.; 6 to 12 mm |
| Pressure Ratings | Fractional Tubing: Up to 4896 psig (337 bar) Metric Tubing: Up to 403 bar (5849 psig) Maximum Process Temperature: 400°F (204°C) |
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. 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.
Specifications
| Materials | 316 or 316L stainless steel, copper, or PFA with PVC or urethane jacket |
| Sizes | 1/4 to 3/4 in.; 6 to 12 mm |
| Pressure Ratings | Fractional Tubing: Up to 10 900 psig (751 bar) Metric Tubing: Up to 420 bar (6095 psig) Maximum Process Temperature: 220°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.
