CUP SEAL

摘要

CUP SEAL The lip of a cup seal for use in a master cylinder incorporates a semi-torus of material extending axially outward from the outer peripheral end of the seal lip. The added material is positioned immediately adjacent, but slightly radially inward from, the sharp lip edge. This added material prevents the lip from hanging up on the edges of compensation ports which open into the master cylinder bore, particularly during initial installation.
