QUAD & SQUARE RINGS

 

SQUARE RING

A Square-Ring is a sealing device made in the form of a torus, with a square shaped cross-section. It is available in a variety of elastomeric and thermoplastic materials. In most static applications, it is  a direct replacement  of an O-RING and generally will perform this high pressure gasketing function as well as, or better than an O-RING.

 

QUAD RING

The quad ring is a self-sealing rubber ring with four rounded sealing lobes. Quad rings were primarily designed to replace o-rings in cases where the application of o-rings is not satisfactory or not suitable at all.
