Bonded Washers


Our Bonded Seals consist of a rubber sealing element that is bonded to the inner wall of a metal washer. They are used in applications where high pressures demand greater sealing capacity that can be obtained with copper washers. Available in a range of materials dependant on the application, in both metric and imperial sizes.


Also known as Dowty seals, bonded seals and washers provide reliable and dependable resistance in high pressure applications. They are particularly suited to sealing under the heads of bolts and threaded components, for Pipe Couplings and a wide range of connector applications where a perfect face-to-face contact is required for sealing gases, oils, and other fluids.
