It measures 0.313 inches inside diameter, 0.563 inches outside diameter, and 0.125 inches thick with a round cross section. Made from Ethylene Propylene Diene Monomer (EPDM) compound with a hardness rating of 70 durometer, this O-ring delivers reliable sealing performance across a wide service temperature range of -65 degrees F to 300 degrees F. Each package contains 100 O-rings. Installation is handled by licensed plumbers, HVAC technicians, and hydraulic system technicians.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for hot water and steam service lines, phosphate ester type hydraulic fluid systems, and commercial aircraft hydraulic systems requiring resistance to Skydrol fluids. It is a practical choice for residential and commercial plumbing repairs, boiler system maintenance, and industrial hydraulic circuit servicing where EPDM compatibility with the process fluid has been confirmed. The Dash 203 designation makes cross-referencing to standard O-ring sizing charts straightforward for trade professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM material provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRated for Skydrol fluid exposure in commercial aircraft hydraulic systems\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness for a firm, reliable seal under pressure\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard Dash 203 O-ring groove dimensions\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for shop stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with hot water, steam, and phosphate ester hydraulic fluid systems.
