It features a round cross-section measuring 7.75 inches inside diameter, 7.938 inches outside diameter, and 0.0937 inches thick. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 250 degrees F, this O-ring delivers reliable sealing performance across a wide range of hydraulic, pneumatic, and mechanical assemblies. Plumbers, pipefitters, millwrights, and maintenance technicians install this type of seal in applications where petroleum-based fluid compatibility is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic oil systems, fuel handling equipment, and general industrial fluid conveyance. Its Buna-N compound provides excellent resistance to petroleum products along with good compression set resistance and strong tear and abrasion resistance. It meets SAE and MIL-Spec standards, making it appropriate for both commercial maintenance and light industrial service environments. The package quantity is 25 pieces per unit, sold in multiples of 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound with excellent petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross-section for standard O-ring groove fitment\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eResists tear, abrasion, and compression set in service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based fluids and oils. Designed as an OEM-style replacement or maintenance-stock O-ring for Dash 170 groove specifications in hydraulic, pneumatic, and general fluid-sealing assemblies.

Shut off and depressurize the fluid system completely before removing the old O-ring or installing the new one. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent pinching or tearing during assembly. Do not store O-rings in direct sunlight or near motors or other equipment that may generate ozone, as this degrades the elastomer over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 170\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 Fluids\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 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH70170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704906350898,"sku":"ZMSCH70170","price":20.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57f97a549e020b288e8889e308b3b479.jpg?v=1788425682","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70170-o-ring-dash-170-nitrile-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
