8.4mm x 25mm Bonded Sealing Washer | 2.8mm | A2 Stainless Steel & EPDM
For automotive and transport components requiring a sealed fastener point, this 8.4mm x 25mm stainless steel bonded washer combines load spreading from the stainless steel ring with the sealing action of EPDM Rubber. The bonded construction keeps the metal washer and rubber seal together as one component for straightforward fitting.
What Are Bonded Sealing Washers?
Bonded Seal Washers, often referred to as Dowty washers, use a metal outer washer bonded to a rubber sealing section. The metal component provides support and load distribution while the elastomer compresses to help seal the fixing hole.
These bolt sealing washers combine a metal support ring with a bonded elastomer seal for suitable bolted and screwed connections.
Common Applications
- Pipework and Fittings: Can help seal compatible threaded fixing points and connections where the fluid and operating conditions are suitable for EPDM.
- Machinery: Provides a bonded seal around suitable bolts used on guards, covers and equipment housings.
- Perspex and Sheet Materials: Spreads clamping force through the metal washer while the EPDM layer cushions the contact surface.
- Maintenance and Repair: Provides a one-piece replacement where both a washer and compressible seal are required around a fixing.
