What are Bonded Seals?

Bonded Seals are sealing washers. A sealing bead is vulcanized onto a metal washer to achieve the sealing effect. 

Bonded Seals are available in various sizes and can be supplied with an elastomer lip on the outer circumference or on the edge of the inner hole, giving a wide range of possible applications.


Bonded Seals are used as seals against excess pressure. Like commercially available washers, they are used on screws to seal openings impermeably to various media. 

Compared to conventional sealing rings made of soft metal, they have the advantage of being able to withstand very high pressures and have a self-sealing effect. They are therefore used in hydraulic systems, on pressure vessels or on engines (oil and fuel systems).
