Types of Bonded Sealing Washers We Offer

Bonded Sealing Washer Galvanized

Bonded sealing washers with a galvanized finish are designed to create both a mechanical hold and a weather-tight seal. The bonded layer, typically rubber or neoprene, compresses under load to prevent leaks, while the galvanized steel body provides strength and corrosion resistance. These washers are widely used in roofing, siding, and outdoor construction where fasteners are exposed to the elements. Contractors rely on them for projects requiring both secure fastening and long-term protection against moisture. Their combination of durability and sealing capability makes them an essential choice in exterior applications.

Material Options

South Coast Fasteners stocks bonded sealing washers in steel, providing the strength and compression needed to keep the sealing layer secure under pressure.

Steel

Steel bonded sealing washers deliver the durability and holding power required for demanding jobs. The steel body provides the structure, while the bonded sealing layer takes care of keeping joints watertight or airtight. These washers are trusted in environments where vibration, temperature changes, or direct exposure would compromise a standard washer. They are relied on in construction, mechanical systems, and utility installations where long-lasting performance is essential.

Available Finishes

South Coast Fasteners offers bonded sealing washers with finishes that add corrosion protection and extend service life in harsh environments.

Galvanized

Galvanized bonded sealing washers feature a zinc coating that protects the steel against rust. This finish makes them especially effective in outdoor or wet conditions, where moisture and weather exposure would otherwise cause premature failure. They are the practical choice for roofing, exterior HVAC work, and utility applications where long-term reliability is critical.
