Bonded Seals/ Washer Seals
The combination of a rubber sealing lip and a metal gasket is specifically designed for high-pressure pipelines and threaded joints, providing superior leak-proof sealing.
Description
- A bonded design combining an elastomer sealing lip with a metal washer
- Designed to provide reliable leak prevention in high-pressure piping systems and threaded connections
- As the bolt is tightened, the sealing lip is compressed against the mating surface while the metal washer controls compression and supports the seal, ensuring reliable and stable sealing performance
