It measures 0.739 inches inside diameter, 0.879 inches outside diameter, and 0.07 inches cross-section thickness. The round cross-section profile seats evenly in standard O-ring grooves, maintaining a leak-free seal under pressure. Black in color, this O-ring is manufactured from Buna-N, a material well-suited for use with petroleum-based fluids, water, and many common industrial media. Licensed plumbers, HVAC technicians, and fluid-systems mechanics install this type of seal when servicing valves, fittings, pumps, and related components.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for residential and light commercial applications wherever a standardized seal of this size is required. Common installation scenarios include valve body rebuilds, pump seal replacements, and threaded fitting connections in plumbing, HVAC, and general fluid-handling assemblies. Buna-N material makes it a practical choice for systems running water, oils, or hydrocarbon-based fluids within the material's rated temperature and chemical compatibility range. Always verify the groove dimensions and fluid compatibility before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.739 inches inside diameter for precise groove fitment\u003c\/li\u003e\n\u003cli\u003e0.879 inches outside diameter with 0.07 inches round cross-section\u003c\/li\u003e\n\u003cli\u003eBuna-N (nitrile butadiene rubber) construction for compatibility with petroleum fluids and water\u003c\/li\u003e\n\u003cli\u003eRound cross-section seats uniformly in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eBlack color for easy visual identification during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement seal for valves, pumps, fittings, and fluid-handling components requiring a 0.739 inches ID x 0.879 inches OD Buna-N O-ring with a round cross-section profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanic familiar with sealing system service procedures. Always depressurize and isolate the system before removing or installing O-rings. Lightly lubricate the O-ring with a compatible grease or fluid to prevent tearing during installation. Inspect the groove for nicks, burrs, or debris before seating the new seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.739 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.879 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4629X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51542925836594,"sku":"4629X12","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c0fd7c375e00bffccd28c8bc48fbdd0.jpg?v=1785911188","url":"https:\/\/voomisupply.com\/products\/eaton-4629x12-o-ring-0-739-in-id-buna-n-black","provider":"Voomi Supply","version":"1.0","type":"link"}
