It measures 1.25 inches inside diameter, 1.5 inches outside diameter, and 0.125 inches thick with a round cross section. The silicone compound provides reliable performance across a wide temperature range, from -80 degrees F to 450 degrees F, making it well suited for high-heat and outdoor-exposure environments. Hardness is rated at 70 Shore A. This O-ring is sold in a package of 50 and is installed by HVAC technicians, plumbers, and mechanical service professionals.\u003c\/p\u003e\n\u003cp\u003eThis O-ring fits applications requiring good dry heat resistance, weather resistance, and ozone resistance. It offers limited oil resistance and is compatible with oils, chemicals, and solvents in appropriate concentrations. Typical installation scenarios include equipment connections, valve stems, pump housings, and threaded fittings in residential and light commercial mechanical systems where temperature extremes or outdoor exposure are concerns. The round cross section seats cleanly in standard O-ring grooves sized for Dash 218 dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWide service temperature range: -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating in standard Dash 218 grooves\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for firm, reliable sealing\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in suitable concentrations\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 supports service stock and bulk repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 218 O-ring replacement for any application requiring a 1.25-inch ID, 1.5-inch OD, 0.125-inch thick round cross section silicone seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians, plumbers, or qualified mechanical service professionals.
