Your Authorized Swagelok Product and Service Center

Swagelok is known for its tube fittings and their exceptional performance. But do you know what leads to such low leak rates?

This demonstration by our founder, Fred Lennon, explains what is happening at each quarter turn during installation of a Swagelok tube fitting. This is the low tech but highly interactive way of showing the functioning of the fittings. For years, this design has provided the effect that Swagelok customers around the world have come to trust, unfailing reliability and peace of mind. Read more of our customers' stories here.

As video technology has improved, we now have excellent graphics that can demonstrate exactly what is going on in a cross-sectional representation. Below is our Finite Element Analysis (FEA) video that explains how the fittings stay on and how they produce a gas-proof barrier. The step-by-step analysis starts at :44, before that is a brief explanation of the mathematical model is used to create the imagery.


Although our way of describing why our fittings perform so well has changed dramatically in the last 70 years, our fittings have remained reliable throughout that entire time.
