Swagelok® Tube Fittings and Adapters
Reduce leaks and downtime with two-ferrule tube fittings that have leak-tight seals, superior tube grip, and vibration resistance, even after reassembly.
Tube Fittings | Easy to install helping to reduce installer fatigue.
Tube Adapters | Enable various connections and help eliminate difficult alignment issues.
Swagelok fittings outperform others in reducing the risk of leaks and costly downtime across various industries. The advanced back ferrule design isolates stress to resist vibration, bending, and deflection, while a patented carburization process enhances strength without sacrificing corrosion resistance. Easy to install and reassemble, Swagelok fittings require less effort than alternatives.
Tube fittings and adapter fittings are available in multiple alloys to ensure chemical compatibility, with expert-led training offered for proper installation. Swagelok tube adapters can be used with any other Swagelok tube fittings eliminating the need for stocking special elbows and tees. Stainless steel Swagelok tube fittings used with 316 stainless steel and 316 Ti stainless steel alloy tubing have been tested to the requirements of ECE R110 and are also available with EC-79 certification. Swagelok offers fittings in materials that meet the metallurgical requirements of NACE MR0175/ISO 15156 and MR0103. Also, fittings manufactured from alloy 2507 and 6MO are NORSOK M-630 and M-650 compliant as standard.

Swagelok Founder Explains His Revolutionary Tube Fitting
More than 75 years later, the Swagelok tube fitting, with its unique “hinging-colleting” action, remains trusted to provide lasting, leak-tight service. The grip-type design uses the “hinging and colleting” action to achieve optimal performance in three key areas:
Tube Grip
The hinging and colleting action provides more direct tube contact/gripping support.
Gas Seal
The burnishing/polishing action of the front ferrule creates concentrated zones of contact on the tube and on the body bevel for a stronger seal.
Vibration Resistance
The colleting region better isolates stress risers at the tube grip to resist bending, deflection, and vibration.
Swagelok® Tube Fitting Design
The advanced-geometry, hinging-colleting back ferrule design is standard on all 1/4 to 1 in. and 6 to 25 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.
