Bonded seals represent a combination of metal washer and elastomer sealing lip. Vulcanised to the edge of the metal part and was originally designed to replace cooper type washers in pressure systems.

Materials

NBR
FKM
Metal- anti-corrosion plated

Function

When the bolted connection is tightened, the sealing lip is pressed against the flat surfaces. The thickness of the metal ring limits the deformation of the elastomer seal. The internal pressure increases the sealing force by energising the sealing lip.

Media

Mineral oils, water, water–oil emulsion, gases

Operational application limits
