The E3X119.5 is a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 119.5 mm (4.705 in), a cross section of 3 mm (0.118 in), and an outside diameter of 125.5 mm (4.94 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.
It resists water and steam, ozone, UV and weathering, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers very good flexibility at low temperature, strong performance in outdoor and exposed installations. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It is not the right choice where aromatic hydrocarbons or petroleum oils and fuels are present.
Common environments for this compound include potable water applications, HVAC and refrigeration, and solar and roofing assemblies.
E3X119.5 ships individually. Review your operating media and conditions against this specification before installation.
