It measures 8.75 inches inside diameter and 8.938 inches outside diameter with a cross-section thickness of 0.0937 inches (3\/32 inches). The round cross-section profile and 70 Shore A hardness rating make it well-suited for static and low-cycle dynamic sealing tasks. Petroleum-product compatibility and solid compression-set resistance are the defining performance characteristics of this material. Licensed trades and maintenance professionals use Buna-N O-rings wherever fuel, oil, or water lines require a reliable face or radial seal.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for residential and light commercial sealing applications involving petroleum-based fluids, water, and compatible hydraulic media. It is commonly installed in pump housings, valve bodies, filter housings, pipe fittings, and fluid-system flanges. The working temperature range of -40 degrees F to 250 degrees F covers the majority of HVAC, plumbing, and general mechanical service conditions. This SKU is packaged in quantities of 25, with a minimum order quantity of 1 package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material offers excellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n\u003cli\u003e8.75 inches inside diameter and 8.938 inches outside diameter with 0.0937-inch round cross-section\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating provides a firm, reliable seal under compression\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eGood tear and abrasion resistance for extended service life in fluid-handling systems\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards for dimensional and material compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products, oils, fuels, and water in standard sealing applications. Not recommended for use with ozone, strong oxidizing agents, or systems that generate direct ozone exposure. Not FDA approved. Designed as a Dash 174 O-ring for use wherever AS568 Dash 174 cross-section dimensions are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians during pump, valve, or fitting service. Shut down and depressurize the system fully before removing or installing O-rings. Lubricate the O-ring with a compatible fluid or grease to ease installation and reduce the risk of tearing during assembly. Do not store Buna-N O-rings in direct sunlight or near motors and other electrical equipment that may produce ozone, as ozone exposure degrades nitrile rubber.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.938 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: 174\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\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\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\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: ZMSCH70174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709322363186,"sku":"ZMSCH70174","price":23.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a93a3545de4c9e6c9ac7a62890df6ab6.jpg?v=1788454592","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70174-o-ring-dash-174-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
