An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists dilute acids and alkalis, water and steam, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) delivers good electrical insulating characteristics, excellent hot water and steam resistance. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C).
Common environments for this compound include outdoor equipment, water and steam systems, and brake and phosphate ester systems.
