Bonded Sealing Washers
Click image to enlarge
Bonded sealing washers feature two components- a silicone rubber flat circle with a galvanized metal backing. These washers are primarily used for vibration absorption and weatherproofing. The threaded fastener, often times a screw, will be inserted through the center of the flat washer so that it rests between the head of the bolt and the connecting material. The galvanized backing should be snug against the head of the bolt with the rubber side against the connecting material. Fasteners Etc can supply the bonded sealing washers and screws as two, separate components or we're happy to assemble them as a single unit to held reduce labor cost and time in the field. If you need a larger outside diameter washer, let us know the requirements for a custom quote.
