It measures 3.5 inches inside diameter, 3.875 inches outside diameter, and 0.1875 inches thick with a round cross section. Rated at 70 Shore A hardness, it delivers reliable sealing performance in systems that handle petroleum-based fluids. Licensed trades including plumbers, HVAC technicians, and industrial maintenance mechanics install this type of O-ring in hydraulic, pneumatic, and fluid-handling assemblies where a durable, compression-resistant seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum products, hydraulic oils, fuels, and related media. Its operating temperature range spans -40 degrees F to 250 degrees F, making it appropriate for a broad range of mechanical and fluid systems. It is commonly installed in valve bodies, pump housings, fittings, and manifold assemblies where a standard Dash 341 cross-section O-ring is specified. It is sold in packages of 25, making it practical for service shops and field technicians who replace O-rings regularly during preventive maintenance or component rebuilds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) construction offers excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness provides a firm, compression-resistant seal with good tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard Dash 341 O-ring groove dimensions\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F suits most mechanical fluid systems\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 supports shop stock and multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 341 replacement O-ring compatible with petroleum products, hydraulic oils, and related media in systems that specify a Buna-N round-cross-section O-ring of this size.

Clean the groove and mating surfaces thoroughly before seating the new O-ring to prevent extrusion or premature failure. Avoid storing Buna-N O-rings in direct sunlight or near motors and other equipment that generate ozone, as ozone degrades nitrile rubber. Lubricate the O-ring with a compatible fluid or grease during installation to ease seating and reduce the risk of tearing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 341\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\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH70341\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721140961586,"sku":"ZMSCH70341","price":15.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e4c15c6d6094c8a7022245aaa98dddf.jpg?v=1788574266","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70341-o-ring-dash-341-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
