EPDM O-Rings

Professional-Grade EPDM O-Rings for Scuba and Oxygen-Compatible Applications

Our EPDM O-Rings are high-quality sealing components designed for use in scuba regulators, valves, and cylinder systems requiring oxygen-compatible materials.

Manufactured from EPDM (Ethylene Propylene Diene Monomer) elastomer, these O-rings provide excellent resistance to oxygen exposure, moisture, ozone, and a wide range of environmental conditions. EPDM is the preferred material for Nitrox and oxygen-clean applications due to its chemical stability and compatibility with oxygen-safe lubricants such as Christo-Lube®.

These O-rings are ideal for use during regulator overhauls, valve rebuilds, and cylinder service procedures where material compatibility and long-term sealing integrity are critical.
