Bonded seals

Bonded seals are metal washers with a trapezoidal elastomer sealing lip vulcanized to their inner diameter.

Advantages

The bonded seal provides a good security solution in the industrial sector and solves many static sealing problems. They are particularly used as static seals for screw connections and flange seals.

Function

The bonded seal provides a comprehensive security solution for problems of resistance to pressure and vibration under extreme temperature conditions. The laterally outward pressure causes the contact of the lips on the sealing surfaces. A complete seal is achieved both during stationary operation and at pressures of about 700 bar.

Material

The standard BS rings are available in the following combination:

• Washer: carbon steel treated against corrosion,
• NBR 90 SH.

Further special types of bonded seals or according to customers drawings are available on request.
