It carries a Dash 339 designation with an inside diameter of 3.25 inches, an outside diameter of 3.625 inches, and a thickness of 0.1875 inches. The silicone compound provides a wide service temperature range, from -80 degrees F to 450 degrees F, along with solid resistance to dry heat, weathering, and ozone exposure. Licensed trades and maintenance professionals install this O-ring wherever a reliable face or radial seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and commercial plumbing, HVAC equipment, and general mechanical assemblies that involve oils, chemicals, or solvents. Its silicone material performs well in applications that cycle through extreme temperature swings or are exposed to outdoor ambient conditions. The Dash 339 standard size makes it a straightforward drop-in replacement for worn or failed seals in similarly rated equipment. The pack quantity of 5 supports service calls where multiple seals may need replacement or where a job-site stock is preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F for wide temperature range service\u003c\/li\u003e\n\u003cli\u003eDash 339 standard designation: 3.25 inches ID, 3.625 inches OD, 0.1875 inches thick\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for consistent compression and 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 typical mechanical sealing environments\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 5 to support multi-point service or field stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 339 silicone O-ring replacement suitable for plumbing, HVAC, and general mechanical sealing applications requiring a 3.25-inch inside diameter seal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician following applicable plumbing or mechanical codes.
