Bonded seals (also known as Dowty Seals or Dowty Washers) are based on a rectangular section metal washer with a trapezoidal shaped ring of vulcanised rubber bonded to the inside. The metal ring resists the bursting forces and limits the deformation of the rubber sealing element. The seal is primarily used in high-pressure environments where copper washers are unsuitable. Both the metal washer and the rubber material can be selected to suit a given application.
These seals are readily available in Imperial sizes from 1/8 inch to 3 inches. French and German Metric also form part of our extensive stocks at our facility in East Kilbride. For full sizing catalogue with material specifications table please click here.
Bovill & Boyd can provide bonded seals to meet the requirements of a wide range of applications including Aerospace specifications, Drinking Water applications, Gas applications and Automotive specifications.
The rubber sealing ring is mostly supplied in black but coloured compounds can be supplied on request.
A further alternative is Self Centralising Bonded Seals which have an extra lip on the ID of the rubber. This centres the seal at its location and will eliminate leaks due to seal offset with the added advantages of easy installation and reduced assembly time.
