An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against dilute acids and alkalis, ozone, UV and weathering, and ketones. That behavior comes from the compound itself: EPDM (EPR) is specified for strong performance in outdoor and exposed installations, good electrical insulating characteristics. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C).

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in brake and phosphate ester systems, water and steam systems, and potable water applications.
