Why Choose Bonded Seals from O.S Seals?

Bonded Seals, also recognized as Dowty seals or Dowty washers, stand as the preferred choice for sealing excellence in high-pressure mechanical, hydraulic, and pneumatic systems. Explore the advantages that set our Bonded Seals apart:

1. Superior Design for High-Pressure Applications:

Originally crafted to replace traditional copper-type washers in high-pressure systems, Bonded Seals feature an outer ring of robust steel and an inner ring of elastomeric material. This design ensures exceptional performance under pressure.

2. Increased Pressure Resistance:

The compression of the elastomeric material between the bonded seal’s faces provides a secure and efficient seal. The heat and pressure bonding process enhances resistance to bursting, elevating the pressure rating of the seal.

3. Simplified Machining and Installation:

The unique design of Bonded Seals eliminates the need for intricate machining of parts to retain the gasket. This simplicity, in turn, streamlines installation processes, distinguishing them from other seals like O-rings.

4. Self-Centering Technology:

Our range includes self-centering bonded washers featuring an additional rubber flap on the internal diameter. This innovation ensures precise placement at the center of the hole, eliminating seal offset and facilitating effortless installation.

Materials Tailored to Your Application:

Choose from a variety of metal washer types, including Mild Steel, Stainless Steel, Aluminium, or Brass, combined with elastomeric materials such as Nitrile, Viton, EPDM, or Silicone. Our diverse material combinations cater to specific application requirements.

Extensive Size Options:

O.S Seals provides both standard and Self-Centering styles in a comprehensive range of Imperial, Metric, German Metric, and French Metric sizes. From small to large, we offer a variety of sizes to accommodate your unique needs.
