Product Description

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
