BONDED SEALS

The bonded seal is a metal washer with a vulcanised rubber insert and are often referred to as Dowty Washers. They have a rectangular section metal washer with a trapezoidal shaped insert ring of vulcanised rubber bonded to the inside diameter which gives use for sealing in high pressure applications where copper washers have traditionally been used. The metal washer prevents over compression, thus limiting deformation, of the elastomeric ring.

Available in a wide range of metals and elastomers to meet specific application requirements and also a range of sizes in BSP, JIC, German and French Metric, these Bonded Washers are now also available in self centralising form which eliminates leakage occurring due to seal offset during installation
