O-RING
OR seals are composed of a circular ring with a round cross-section, cured in the mould.
Its dimensions are given by the internal diameter and the diameter of the cross-section.
An OR is the most suitable solution for a large number of both static and dynamic sealing problems.
X-RING
X-Ring seals are suitable for all applications seeking improved performance compared to an O-Ring.
They provide low friction, longer service life and no twisting.
