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 moststatic applications, it is a direct replacement for an O-ring and generally will perform a high pressure gasketing function as well as or better than anO-ring.
Interchangeable with O-rings size for size (Standard AS568A sizes)
Uses same groove as O-ring
Can be used for radial seals
Material is homogenous, no joints, no laminations
Edges accurately formed
Extreme close tolerances held on cross-section, I.D. and O.D.
