It measures 5.5 inches inside diameter, 5.688 inches outside diameter, and 0.0937 inches thick, with a round cross-section profile. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. Licensed plumbers, hydraulic technicians, and maintenance mechanics specify Buna-N O-rings for petroleum-based fluid systems due to the material's proven compatibility with oils, fuels, and hydraulic fluids.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications in residential and commercial plumbing, hydraulic systems, pneumatic equipment, and general industrial fluid handling where petroleum-based media are present. Its operating temperature range of -40 degrees F to 250 degrees F covers a wide variety of service conditions. Packaged in quantities of 25 per unit, it is appropriate for high-volume service shops, maintenance departments, and field technicians who need reliable stock on hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products including oils, fuels, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides a firm, durable seal with strong compression set performance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to standard O-ring groove dimensions for Dash 161\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eStore away from direct sunlight and ozone-generating electrical equipment to maintain material integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 161 O-ring replacement compatible with petroleum-based fluids and lubricants.

Relieve all system pressure and depressurize fluid lines completely before removing the existing O-ring. Lightly lubricate the O-ring with a compatible petroleum-based lubricant prior to seating to prevent pinching or tearing during installation. Inspect the groove for burrs or surface damage before fitting the new O-ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 161\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\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: ZMSCH70161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691898110258,"sku":"ZMSCH70161","price":15.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7628f752d31952f31345f05eeb058702.jpg?v=1788290897","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70161-o-ring-dash-161-nitrile-70a","provider":"Voomi Supply","version":"1.0","type":"link"}
