Bonded Washers
A bonded seal (commonly known as a Dowty seal) consists of a metal washer with a vulcanised rubber insert to provide resistance in high pressure applications, particularly suitable for 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. Bonded seals are now available in self-centralising form, which eliminates seal offset and makes for easier installation.    Available in Imperial, German Metric and French Metric sizes and various metals and sealing materials to suit your application.
