Waterproofing solutions for various screws 05 July 2024

The EPDM bonded washer from UTA is a simple pressure gasket, which provides leak-proof sealing from water, gases and other fluids – making it suitable for applications with various screw connections.

The conical design directs flow of facing materials to form a seal conforming to both the fastener and sealing surface. The EPDM rubber can also vulcanise to a variety of metal materials to ensure a robust and enduring bond, making it suitable for a number of applications including stainless steel, galvanised steel, aluminium, as well as galvalume.

With a temperature resistance ranging from -40°C to 200°C (428°F), the EPDM bonded washers are available in M4, M5, M6, M8, M10 and M12 variants with outer diameters of 9.5mm – 29mm.

“We have grown to a remarkable position in the sealing washer market and we are dedicated to providing customers with diverse sealing solutions. Our high-quality bonded washers are widely used in industrial, commercial and residential construction, giving our products an international reputation as reliable, trouble-free sealing and cushioning washers,” comments UTA Auto Industrial Co Ltd.
