Request Information

The Omega Seal is a good choice for the most demanding high pressure gas or liquid applications. The Omega Seal is also a good choice for vacuum seals.

Our Omega Seal offers the lowest leakage rate of all seals available, and is an optimal solution for applications that remain undisturbed for long periods. It’s knife-edge seal contact feature concentrates load force to create an effective seal. A deformable coating material on the seal flows into surface grooves and asperities better than any other seal. Precision manufacturing carefully controls wall thickness and end profile for efficient sealing, while coatings increase the seal’s effectiveness.

JETSEAL is one of the world’s leading manufacturers of Omega Seals.
