Non-Conductive Double Seal Washer, Aluminium, 12g/14g, OD 25mm

Our non-conductive double seal washer is made from high quality EPDM rubber and aluminium. Made for 12 gauge and 14 gauge roofing screws/fasteners, it features a 25mm outside diameter. Specifically designed for cyclonic roofing applications, it provides protection against leaks while stopping electricity and corrosion from passing between connected parts.

Cyclonic roofing installations use specialised fixing methods and materials to help secure a building’s roof against extreme wind uplift and powerful gusts during tropical cyclones. Using the correct washer is an essential part of the specified fixing system, helping support the connection between the screw and roofing sheet.

The high quality EPDM provides excellent resistance against UV, ozone and corrosion. While offering long lasting leak protection and resistance to over-compression. Requiring less tightening torque than conventional rubber washers, an additional EPDM seal provides further sealing support.
