Why Choose 18-8 Stainless Steel Sealing & Cushioning Washers?

Our 18-8 stainless steel sealing & cushioning washers at AlbanyCountyFasteners.com are designed for leak-proof fastening and vibration dampening in demanding applications. Also known as 18-8 stainless steel bonded sealing washers, these washers feature a neoprene layer bonded to an 18-8 stainless steel backing, equivalent to 304 stainless steel, providing corrosion resistance for non-marine outdoor environments. The neoprene creates a tight seal to prevent water and air leaks while cushioning fragile surfaces and reducing noise and vibration. Compatible with bolts and screws in imperial sizes like #8, #10, 1/4", 5/16", and 3/8", they’re ideal for secure, durable assemblies.
