Bonded Sealing Washer in A2 Stainless Steel

Sealing Washers with a bonded EPDM rubber lay er. Bonded sealing washers are typically used with hex head flanged self drilling screws. As the screw is tightened, the EPDM rubber on the sealing washer will compress and create a water and air tight seal, between the screw and the bearing surface. Bonded sealing washers are widely used in the construction and solar industries. EPDM (Ethylene Propylene Diene Monomer) is a long-lasting synthetic rubber, which maintain it's flexibility and sealing properties at high and low temperatures. It is resistant to UV radiation making it suitable for roofing and outdoor plumbing and electrical structures. EPDM also has a chemical resistance and has good electrical and sound insulation properties.
