Ordered as E70NSF133, this is an AS568-133 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to ozone, UV and weathering, water and steam, and ketones. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.
This item meets FDA requirements for food contact and carries NSF listing. You will find this material specified across water and steam systems, brake and phosphate ester systems, and solar and roofing assemblies.
E70NSF133 ships individually. Unit weight is approximately 0.967 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
