The E70049 is an AS568-049 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 4.989 in (126.72 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.129 in (130.28 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to phosphate ester hydraulic fluids, ketones, and water and steam. EPDM (EPR) is known for excellent hot water and steam resistance, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.
Common environments for this compound include water and steam systems, solar and roofing assemblies, and brake and phosphate ester systems.
E70049 ships individually. Unit weight is approximately 1.177 g and nominal inside diameter is listed as 5 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
