Stainless 18 8 Epdm Bonded Washer (Inch)
Our Stainless Steel 18‑8 EPDM Bonded Washers are sealing fasteners designed to provide both load distribution and weather‑tight sealing in bolted assemblies. Manufactured with a stainless steel 18‑8 (Type 304 equivalent) outer washer bonded to an EPDM rubber sealing element, these washers offer excellent corrosion resistance along with dependable sealing performance.
The bonded EPDM gasket compresses under tightening to create a watertight and airtight seal, helping prevent leaks, vibration loosening, and moisture intrusion. Stainless 18‑8 construction provides strong resistance to rust and oxidation, while EPDM rubber offers excellent resistance to UV exposure, ozone, water, and a wide temperature range.
Designed for durability and sealing reliability, 18‑8 Stainless EPDM Bonded Washers are commonly used in roofing systems, enclosures, HVAC installations, electrical panels, outdoor equipment, and general industrial assemblies where sealing and corrosion resistance are critical. The metal washer provides structural support and clamp load distribution, while the EPDM layer ensures long‑term sealing without cracking or hardening. Available in a wide range of sizes, these bonded washers deliver a dependable fastening solution for OEM manufacturing, construction, and maintenance applications.
