Bonded Seals

The Bonded Seal was originally designed to replace copper type washers in high-pressure systems.

The Bonded Seal comprises a metal washer and an elastomeric ring bonded inside the diameter. The metal washer prevents over-compression and limits deformation of the elastomeric ring.

Advantages

  • Reliable low and high pressure sealing
  • High and low temperature capabilities
  • Bolt torque is reduced with no loss of tightening load

Materials

Elastomer component is available in NBR 70 and NBR 90

Washer component is carbon steel, zinc/yellow zinc plated or stainless steel (on request).
