Bonded Seals (UK)

Bonded Seals are also known as Dowty Seals or Dowty Bonded Washers. They are high pressure seals used in the Mechanical, Hydraulic and Pneumatic sectors. Bonded Seals have replaced copper washers in high pressure applications.

Although the most popular choice is for a Nitrile Rubber Seal with a Zinc Plated outer, various choices are available both of the rubber insert and the metal outer. Rubber variations include Viton, Silicone, and EPDM etc while the metal outer options include Stainless Steel, Brass, Aluminium Bronze and Light Alloy.

Why Use Bonded Seals?

Bonded Seals were originally designed to replace copper type washers in high-pressure systems. Bonded Seals comprise of a metal washer and an elastomeric ring bonded inside the diameter. The metal washer prevents over-compression and limits deformation of the elastomeric ring.

Characteristics Of Bonded Seals:

• Ideal Pressure Gasket
• Reliable sealing at high & low pressure
• High & low temperature capability
• Reduced bolt torque with no loss of tightening loads
• Metal ring prevents rubber compression
