It measures 3.475 inches inside diameter, 3.875 inches outside diameter, and 0.1875 inches (3\/16 inches) thick. The compound carries a Shore A hardness of 70 and is rated for service from -40 degrees F to 250 degrees F, making it a dependable choice in a wide range of operating conditions. Each package contains 2 O-rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications where petroleum-based fluid sealing is required. Typical installations include pump housings, valve bodies, pipe unions, and hydraulic cylinder end caps. Buna-N is the most widely used O-ring elastomer in trade work and is compatible with petroleum products, oils, fuels, and many hydraulic fluids. It is installed by plumbers, HVAC technicians, and hydraulic equipment technicians during routine maintenance or component replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating — suitable for both static and dynamic sealing\u003c\/li\u003e\n\u003cli\u003eService temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eExcellent compression set, tear resistance, and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eBlack color; Metal Detectable FDA designation noted (not FDA Approved)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 341 O-ring replacement compatible with petroleum-product and hydraulic fluid service applications where a Buna-N compound with 3.475 inches ID and 0.1875 inches cross-section thickness is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut down and depressurize the system fully before removing the old O-ring. Inspect the groove and mating surfaces for nicks, scoring, or contamination before installing the new O-ring. Lightly lubricate the O-ring with a compatible petroleum-based lubricant prior to installation to reduce the risk of tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this degrades the elastomer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 341\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.475 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 (Cross Section)\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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\u003eColor\u003c\/strong\u003e: Black\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: 2\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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH70MD341\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700406878514,"sku":"ZMSCH70MD341","price":19.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2eee0a0aa40cb902d9c677b5177eb334.jpg?v=1788389953","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md341-nitrile-o-ring-dash-341","provider":"Voomi Supply","version":"1.0","type":"link"}
