What Are EPDM Rubber WRAS Flange Gaskets?
EPDM (Ethylene Propylene Diene Monomer) rubber is a highly durable, weather-resistant elastomer widely used in water distribution systems, industrial pipelines, and HVAC applications.
Unlike standard rubber gaskets, WRAS-approved EPDM flange gaskets meet strict UK regulations for potable (drinking) water use, ensuring no contamination, leaching, or taste alteration.
- WRAS-certified for potable water applications
- Temperature resistance from -40°C to +120°C
- Highly durable, UV-resistant, and ozone-resistant
- Flexible and elastic for long-term sealing under compression
- Compatible with water-based fluids and mild chemicals
Whether sealing flanges in a municipal water supply, an industrial processing system, or a commercial HVAC unit, EPDM WRAS gaskets provide reliable, leak-free performance.

Common EPDM WRAS Gasket Challenges and Our Solutions
- Limited Chemical Resistance
EPDM is not suitable for oils, fuels, or solvents. For oil-based applications, use Nitrile or Viton rubber. - Temperature Limitations
EPDM withstands up to +120°C. For higher temperatures, consider PTFE or Silicone gaskets. - Compression Set Over Time
Long-term compression can cause reduced elasticity. Using reinforced EPDM ensures long-lasting performance. - Not Ideal for High-Pressure Sealing
For high-pressure systems, metal-reinforced or PTFE-coated gaskets offer better performance. - Risk of Over-Tightening
Excessive torque can cause gasket extrusion. Always follow manufacturer torque specifications for optimal installation.
FAQs About EPDM WRAS Flange Gaskets
Are EPDM WRAS gaskets safe for drinking water?
Yes, WRAS certification guarantees compliance with UK potable water safety standards.
Can EPDM gaskets handle high temperatures?
EPDM gaskets withstand temperatures up to +120°C, making them ideal for hot and cold water applications.
Are these gaskets chemical-resistant?
EPDM is resistant to mild acids, alkalis, and water-based solutions but is not suitable for oils or petroleum-based chemicals.
How long do EPDM WRAS gaskets last?
EPDM gaskets offer long service life, thanks to their resistance to UV, ozone, and weathering.
