It carries a Dash 026 designation and a Shore A hardness of 70, placing it in the hard hardness rating category. Nitrile is the most widely used O-ring elastomer in trade applications, valued for its excellent resistance to petroleum-based fluids, strong compression set retention, and solid tear and abrasion resistance. Licensed trades including plumbers, HVAC technicians, and hydraulic system technicians commonly stock this size for fluid sealing work across a broad range of service calls.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications involving petroleum products, oils, fuels, and hydraulic fluids. It operates reliably across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for both refrigeration-side low-temperature service and standard hot-fluid plumbing and HVAC applications. It should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone degrades nitrile compounds over time. This listing is sold as a pack of 100 pieces, making it practical for shop stock or high-volume service operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) nitrile material with excellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eShore A 70 durometer hardness for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to -250 degrees F suits a wide range of HVAC and plumbing service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile meets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eStrong tear and abrasion resistance extends service life in dynamic seal applications\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece pack for efficient shop stocking and field inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in grooves and fittings sized to the Dash 026 standard (1.25 inches ID, 1.375 inches OD, 0.0625 inches thick).

Always depressurize and isolate the system before removing the existing seal or inserting a new O-ring. Lightly lubricating the O-ring with a compatible fluid or O-ring lubricant during installation reduces the risk of pinching or tearing. Inspect the mating groove for burrs, corrosion, or dimensional damage before seating the new ring.\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 026\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.375 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\u003eShore A Hardness\u003c\/strong\u003e: 70 (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: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: ZMSCH70026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689739714866,"sku":"ZMSCH70026","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93d40fa98b2b202d380429957ddf1ec5.jpg?v=1788263668","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70026-o-ring-buna-n-dash-026-pack-100","provider":"Voomi Supply","version":"1.0","type":"link"}
