In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, EPDM (EPR) is known for good electrical insulating characteristics, excellent hot water and steam resistance. It resists phosphate ester hydraulic fluids, dilute acids and alkalis, and brake fluid. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Verify compatibility before use with mineral oil-based lubricants or aromatic hydrocarbons.
Typical settings include brake and phosphate ester systems, water and steam systems, and outdoor equipment.
Reference part number E5X43 when ordering; the item is sold individually. Unit weight is approximately 3.778 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
