Rated at 70 Shore A hardness, this O-ring handles a working temperature range of -40 degrees F to 250 degrees F and is compatible with petroleum-based fluids, making it one of the most widely specified elastomers in fluid-sealing applications. Plumbers, HVAC technicians, and industrial maintenance professionals install this part in hydraulic, pneumatic, and fluid-transfer assemblies where reliable static or dynamic sealing is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum-product contact, including hydraulic fittings, plumbing connections, pump seals, and refrigeration or HVAC line fittings. Its Buna-N compound provides strong resistance to oils, fuels, and greases, making it a standard choice when specifying replacements for seals in fluid-handling equipment. The part is sold in packages of 50 with a minimum order quantity of 1, making it practical for both single-repair and stocking purposes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — the most widely used O-ring elastomer for petroleum-fluid environments\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides a firm seal with good compression set resistance\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits most HVAC, plumbing, and hydraulic service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eExcellent tear and abrasion resistance for dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 supports service-van stocking and bulk repair jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products including oils, fuels, and greases.

Before replacing any O-ring, depressurize the system completely and isolate the fluid supply. Lubricate the O-ring with a compatible fluid or assembly lubricant prior to seating to prevent tearing during installation. Do not stretch the O-ring beyond its design groove dimensions, and inspect the mating groove for nicks or burrs that could cause premature seal failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 219\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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 Media\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\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ZMSCH70219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691162796338,"sku":"ZMSCH70219","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db9ac024d28eff18cb388f46a619b750.jpg?v=1788280936","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70219-o-ring-dash-219-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
