An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

At Trans-Tech we have a huge range of o-rings in NBR and Viton material. Non-standard o-rings can now be manufactured by CNC machining.

We have added new stock of viton O-Rings of standard imperial sizes, from cross section 1.78mm to 6.99mm. Contact us today!

Engineers may also be interested in other complementary products installed with o-rings. More information can be found below:
