EPDM Rubber Gaskets

A synthetic elastomer renowned for providing excellent resistance to ageing, ozone degradation and weathering effects, making EPDM the preferred choice for exterior sealing applications. EPDM rubber gaskets feature a watertight surface structure that prevents moisture ingress whilst providing good abrasion and mechanical wear resistance. The polymer's exceptional environmental stability ensures long service life in outdoor installations, weatherproof enclosures and exposed equipment. EPDM maintains its physical properties even under prolonged UV exposure, temperature cycling, and atmospheric contamination. These gaskets are particularly suited to water systems, HVAC equipment, construction applications and any installation requiring reliable outdoor performance. The material's resistance to steam and hot water makes it valuable across diverse industrial sectors. 

If you require an EPDM gasket for use with potable drinking water or with foodstuffs, WRAS / WRc-approved or white food-quality gaskets in these specialist materials can be supplied.

We utilise advanced CNC machinery and can manufacture gaskets to almost any size you require. We convert sheet material into standard flange, picture frame, and dovetail gaskets and can fulfil both low- and high-volume requirements. For information on how to accurately measure your gasket, please see our guide on 'How to Measure a Gasket'.
