Why Choose Aluminum Sealing & Cushioning Washers?

Our aluminum sealing & cushioning washers at AlbanyCountyFasteners.com are designed for lightweight, leak-proof fastening in applications requiring corrosion resistance and vibration dampening. Also known as aluminum bonded sealing washers, these washers feature a neoprene layer bonded to a lightweight aluminum backing, offering corrosion resistance ideal 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 perfect for secure, lightweight assemblies.

  • Lightweight Construction: Aluminum reduces weight in assemblies.
  • Corrosion Resistance: Withstands rust in non-marine outdoor settings.
  • Leak-Proof Seal: Neoprene bonding prevents water and air infiltration.
  • Cushioning: Protects fragile surfaces and dampens vibration.

Applications for Aluminum Sealing & Cushioning Washers

Aluminum bonded sealing washers are tailored for projects requiring lightweight, corrosion-resistant sealing and cushioning in outdoor or high-vibration environments. Their versatility makes them suitable for:

  • Roofing and siding installations
  • HVAC and plumbing assemblies
  • Electronics and circuit board mounting
  • Automotive components requiring lightweight fasteners
