COMPOSITE GASKET

摘要

A composite gasket is formed of soft outer facing layers with a harder tanged material sandwiched in between. The soft outer layers allow the gasket to conform to flange irregularities, while also sealing at low bolt loads. The hard core tangs spear into the body of the facing layers during compression thereby allowing the harder tanged core to securely grip into the soft outer facings and provide a durable core throughout the entire body of the gasket.
