GASKET HAVING A PLIABLE RESILIENT BODY WTIH A PERIMETER HAVING CHARACTERISTICS DIFFERENT THAN THE BODY

摘要

A single piece gasket is disclosed having a skeletal member, typically metallic, and a pliable body. The pliable body includes a first portion having a first firmness and a second perimeter portion have a firmer consistency. When such a composite body is placed under compression, the perimeter will tend to limit the flow of the softer inner material past the firmer perimeter region or portion of the gasket. In this manner, creep or overrun of the less firm portion material will be reduced.
