It measures 6 inches inside diameter with a 6.188 inch outside diameter and a cross-sectional thickness of 0.094 inches (3\/32 inch). The 90 durometer hardness rating places this in the extra-hard range, providing strong resistance to compression set and excellent sealing under pressure. The operating temperature range spans -40 degrees F to 250 degrees F, making it suitable for a broad range of service conditions in HVAC, plumbing, and fluid handling systems. Licensed tradespeople and maintenance technicians install this O-ring anywhere a round cross-section seal is required in petroleum-compatible assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and commercial mechanical systems where petroleum-based fluids, hydraulic oils, or fuels contact the sealing surface. Typical applications include pump housings, valve bodies, pipe unions, manifold fittings, and refrigeration components that do not contact incompatible media such as ozone or certain synthetic fluids. The Buna-N compound delivers reliable tear and abrasion resistance in dynamic and static sealing arrangements. This part is sold in a package quantity of 25 units with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound with excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard hardness rating for reduced compression set and high-pressure sealing\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F covers most HVAC and plumbing service environments\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eGood tear and abrasion resistance for both static and dynamic sealing installations\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 units supports service stock and maintenance kit builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, and similar fluids per the Buna-N material specification.

Always depressurize and isolate the system before removing or replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or grease before installation to reduce the risk of tearing during assembly. Avoid rolling or twisting the O-ring into the groove; seat it evenly to ensure a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 6.000 inches (152.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.188 inches (157.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches \/ 3\/32 inch (2.62 mm)\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: 163\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\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: 90 Durometer (Extra 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: 1.75 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: ZMSCH90163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694861189426,"sku":"ZMSCH90163","price":21.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_0f9c8d91-6cca-4f0a-96b0-44d6b1c548dd.jpg?v=1788329180","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90163-o-ring-6in-id-nitrile-dash-163","provider":"Voomi Supply","version":"1.0","type":"link"}
