  • Envelope gasket
    Patent number: 11268616
    Abstract: An envelope gasket features a bonded construction. In one example, a virgin PTFE envelope is bonded to a pair of microcellular or expanded PTFE filler material annular rings. The PTFE filler annular rings are then bonded together around a corrugated metal insert ring (on the inner and outer diameter), thus sealing inside microcellular or expanded PTFE. Alternatively, when using expanded graphite filler material annular rings, the PTFE envelope is bonded to the expanded graphite filler rings by pressure and heat, and the filler rings are bonded to each other by pressure during the bonding process.
    Type: Grant

  • COMPOSITE GASKET
    Publication number: 20150115548
    Abstract: 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.
