It features a 0.75 inch inside diameter, a 0.875 inch outside diameter, and a 0.0625 inch cross-section thickness with a round cross-section profile. Rated at 70 Shore A hardness, this O-ring delivers strong resistance to petroleum-based fluids, solid compression set performance, and good tear and abrasion resistance. It is sold in a package quantity of 100 and suits high-volume maintenance, repair, and operations (MRO) environments.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for plumbing, HVAC, hydraulic, and pneumatic systems where petroleum-fluid compatibility is required. Common install scenarios include pump seals, valve bodies, fittings, and fluid line connections in residential and light commercial applications. The Buna-N compound performs across a working temperature range of -40 degrees F to 250 degrees F, making it appropriate for a broad range of seasonal and operational conditions. Technicians in plumbing and HVAC trades will find this a dependable stock item for general sealing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction provides excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003e0.75 inch inside diameter, 0.875 inch outside diameter, 0.0625 inch cross-section thickness — standard Dash 018 sizing\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating for durable compression and sealing under pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for consistent groove seating and reliable seal contact\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum-based products and hydraulic fluids.

Always depressurize and isolate the system before replacing any O-ring seal. Inspect the groove for damage or debris before seating the new ring; do not stretch or twist the O-ring during installation. Avoid storing unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N compound over time.\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: 018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Shape\u003c\/strong\u003e: Round\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\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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\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: ZMSCH70018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717503025458,"sku":"ZMSCH70018","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5689f08a70e6a45c78c3f083c89089e1.jpg?v=1788541630","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70018-o-ring-dash-018-nbr-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
