5.3mm x 12mm Bonded Sealing Washer | 2.8mm | A2 Stainless Steel & EPDM
For roofing fixings, cladding and external sheet-metal work, this 5.3mm x 12mm 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.
Different sizes of bolt sealing washers are available for compatible fixings used across construction, engineering and fluid-handling applications.
Common Applications
- Roofing and Cladding: Helps seal compatible screw or bolt fixings through sheet-metal roofing, cladding and exterior panels.
- Industrial Enclosures: Provides a sealing interface around suitable fasteners used on access panels, housings and equipment covers.
- General Construction: Combines load spreading and sealing around compatible bolts used in fabricated metal and external assemblies.
- Outdoor Equipment: A2 Stainless Steel and EPDM construction suits many weather-exposed fastening points where correct sealing is required.
