With a 2.688-inch inside diameter, 2.875-inch outside diameter, and 0.0937-inch (3\/32 inch) cross-section thickness, this round-profile ring seals static and dynamic joints in plumbing, HVAC, pool, and industrial equipment. The silicone compound carries a Shore A hardness of 70 and is rated for service from -80 degrees F to 450 degrees F, making it well suited for environments with dry heat cycling, wide seasonal swings, or ozone exposure. Each order ships as a package of 10 rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in residential and commercial applications wherever a standard Dash 147 silicone seal is required. Typical install scenarios include pump housings, valve bodies, heat exchanger ports, filter canisters, and equipment access covers in HVAC, plumbing, and pool systems. The silicone material offers good weather and ozone resistance and handles moderate chemical and solvent exposure. It is not recommended as a primary seal in high-pressure oil service. Installers often keep a stock of Dash 147 rings on hand for service calls involving common pump and valve assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 147 standard sizing: 2.688 inches ID x 2.875 inches OD x 0.0937 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003eShore A 70 hardness for firm, consistent compression sealing\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for standard groove fitment\u003c\/li\u003e\n\u003cli\u003eGood resistance to weather, ozone, and dry heat cycling\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents in general-duty service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 147 replacement O-ring for any application requiring a 2.688-inch ID silicone seal with a round cross-section profile in plumbing, HVAC, pool, or industrial equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or pool service professionals depending on the application. Shut off and depressurize the system completely before removing the old ring or seating the new one. Clean the groove and mating surface of debris and old sealant before installation.
