EPDM Rubber Gaskets - WRAS / WRc Approved

EPDM Rubber Gaskets - WRAS / WRC Approved  

WRAS / WRc approved EPDM rubber gaskets are cut from a synthetic elastomer that meets the requirements of BS 6920-1:2000 and BS 6920-1:2014 for use with wholesome water up to +23°C. They provide excellent resistance to weathering, ageing and ozone and are commonly used by water authorities in external sealing applications due to the materials impervious surface.

WRAS approved EPDM gaskets have a cloth impression on both sides as standard and can be supplied with a plate finish if required. If industry standards are not critical to your application, we can supply standard EPDM rubber gaskets.

At PAR Group, we have the capability to manufacture bespoke and standard table flange gaskets utilising CNC machinery. If you require help to accurately measure your gasket dimensions, please view our easy to read guide on 'How to Measure a Gasket'.
