ABSTRACT:
An annular seal for providing a seal between a piston member and a cylinder. The seal comprises a resiliently deformable annular member made of elastomeric material having a sealing lip and an axially extending mounting face. The seal includes an annular retaining ring comprising more than one loop of wire which is disposed within and bonded together by the elastomeric material. The piston member includes a mounting surface having an L-shaped cross section which is adapted to receive the sealing member thereon. The retaining ring is designed to resiliently deform the elastomeric material of the sealing member which is located between the retaining ring and the axially directed portion of the mounting surface to provide the sole means for retaining the seal on the piston member.
