It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to ozone, UV and weathering, phosphate ester hydraulic fluids, and dilute acids and alkalis. EPDM (EPR) is known for good electrical insulating characteristics, outstanding weather, ozone and sunlight resistance. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). It is not the right choice where mineral oil-based lubricants or petroleum oils and fuels are present.
This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across brake and phosphate ester systems, potable water applications, and HVAC and refrigeration.
E70NSF022 ships individually. Unit weight is approximately 0.248 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
