Chloramine Resistant | |
Parker’s EJ273-70 is a 70 Shore A black EPDM compound engineered for superior resistance to chloramine and other disinfectants commonly used in potable water systems. Designed to meet ASTM D2000 M4CA710 specifications, it delivers reliable sealing performance in both hot and cold water applications across a service temperature range of -70°F to 250°F. The compound provides excellent resistance to water, steam, ozone, and weathering, along with consistent performance in chloramine-treated environments where standard EPDM materials can degrade. Its stable formulation supports long-term elasticity, low compression set, and dependable sealing integrity over extended service life.
EJ273-70 is well suited for plumbing components, municipal water systems, and other applications requiring compatibility with drinking water and disinfection chemicals. It offers strong aging resistance and mechanical durability under repeated pressure and temperature cycling. Canyon Components offers equivalent EPDM materials designed to meet similar performance requirements for potable water, chloramine-resistant, and steam sealing applications.
