Part number E2.5X8 is a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 8 mm (0.315 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 13 mm (0.51 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to brake fluid, ozone, UV and weathering, and dilute acids and alkalis. That behavior comes from the compound itself: EPDM (EPR) is known for good electrical insulating characteristics and very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.
Typical settings include water and steam systems, solar and roofing assemblies, and potable water applications.
Stocked as E2.5X8 and sold individually. Review your operating media and conditions against this specification before installation.
