摘要

The gasket (1) is made of a polymeric material. The gasket has an inner portion (10), a wall (17) facing an interior of the joint, and an outer portion (11) that forms radial end walls (12, 13). The inner portion is formed with an angled wall (18), which when expands inwardly interacts with a matching angled wall (25) of a seat (2).
