Shock-absorb Waterproof

Bonded® Washer Series

Seals that can effectively waterproof, loosen and shock-absorb

Our bonded washers are seals that can effectively waterproof, loosen, and absorb shock. They are widely used in construction, machinery, home appliances, solar energy, and automobiles.

These bonded washers are made from EPDM bonded with stainless steel, titanium, galvanized steel, aluminum, and copper, ensuring exceptional durability and performance.

Additionally, our bonded washers function as lock washers, effectively changing metal plates from curved surfaces to flat surfaces. This design allows the EPDM to fit tightly against roofing plates, ensuring a secure and waterproof seal.
