WRAS EPDM rubber seals

WRAS EPDM Seals – Premium Sealing Solutions for Potable Water

Advanced Seals & Gaskets Ltd (ASG) specialises in manufacturing high-quality WRAS EPDM seals in the UK, offering superior protection against leaks, contamination, and ingress of air, fluids, or gases. Our EPDM rubber seals come in a variety of forms, including gaskets, washers, O-rings, strips, and extrusions, and are customised to your exact specifications using drawings, samples, or measurements.

Our investment in state-of-the-art machinery enables us to produce both low-volume prototypes and high-volume runs, ensuring consistent quality across all WRAS-approved EPDM rubber seals. These seals are designed to prevent water contamination, reduce vibration, and fill gaps between uneven surfaces, making them ideal for drinking water systems and industrial applications.

What Are WRAS EPDM Rubber Seals?

EPDM (Ethylene Propylene Diene Monomer) rubber is a durable, synthetic elastomer widely used for sealing applications. WRAS-approved EPDM seals meet the strict standards of the Water Regulations Advisory Scheme (WRAS), making them suitable for use with potable water and ensuring safe use in water storage, dispensing, and transport systems.

These WRAS EPDM seals are produced with a cloth-impression on both faces, providing an impervious surface to contain water and prevent contamination. Common forms include:

  • Cut gaskets

  • Washers

  • O-rings

  • Extruded profiles

  • Cord

EPDM rubber seals are versatile and reliable, creating barriers to protect liquids, gases, and particles in demanding environments.
