It measures 0.924 inches inside diameter and 1.125 inches outside diameter with a 0.0937-inch thickness. Rated at 70 Shore A hardness, it operates across a temperature range of -40 degrees F to 250 degrees F. Buna-N is the most widely used O-ring elastomer in the trade, chosen for its excellent resistance to petroleum-based products, strong compression set performance, and solid tear and abrasion resistance. Licensed plumbers, HVAC technicians, and mechanical contractors install these as standard sealing components in refrigerant, hydraulic, fuel, and compressed-air circuits.\u003c\/p\u003e\u003cp\u003eThis O-ring is well suited for residential and commercial plumbing, HVAC refrigerant piping, hydraulic fittings, fuel system connections, and general industrial sealing applications where petroleum-product compatibility is required. The Dash 119 sizing is a standard AS568 dimension used across a broad range of fittings, valves, and connectors. It is compatible with petroleum-based fluids and oils, making it a common choice in equipment service and maintenance scenarios. Note that this material should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades nitrile rubber over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (nitrile butadiene rubber) construction with excellent petroleum-product resistance\u003c\/li\u003e\n\u003cli\u003eDash 119 standard AS568 sizing: 0.924 inches ID x 1.125 inches OD x 0.0937 inches thick\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating for reliable compression set and sealing force\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\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 fluids.

Always relieve system pressure and isolate the fluid supply before disassembling any fitting or valve housing to replace the seal. Inspect the mating groove for burrs, scoring, or contamination before installing the new O-ring. Avoid exposing the installed or stored O-ring to direct sunlight, ozone sources, or strong solvents incompatible with nitrile rubber.\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: 119\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.924 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 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: 0.18 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: ZMSCH70119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705300517170,"sku":"ZMSCH70119","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/535034a28bf639cf15930e87216f9394.jpg?v=1788428072","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70119-o-ring-dash-119-nbr-pack-100","provider":"Voomi Supply","version":"1.0","type":"link"}
