Manufactured from Nitrile Butadiene Rubber (Buna-N), this round cross-section O-ring measures 0.924 inches inner diameter, 1.156 inches outer diameter, and 0.116 inches thick. It carries a Shore A hardness of 70, placing it in the hard rating category. Buna-N is the most widely used O-ring elastomer, offering excellent resistance to petroleum-based fluids, good compression set characteristics, and strong tear and abrasion resistance. Licensed HVAC technicians, plumbers, and fluid-system mechanics install this type of seal during fitting assembly and routine maintenance.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic, pneumatic, and plumbing systems where contact with petroleum products is expected. It is rated for a temperature range of -40 degrees F to 250 degrees F, making it appropriate for a broad range of residential and light commercial service environments. The O-ring boss gasket configuration is specifically intended for straight-thread tube fitting connections, where it seats in a machined boss to form a static face seal. It conforms to SAE and MIL-Spec standards. This item is sold in packages of 100 with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eDash 912 O-ring boss gasket for straight-thread tube fitting applications\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for reliable compression set and sealing performance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile; black color\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based fluids and hydraulic media. Designed as an O-ring boss gasket for straight-thread tube fittings per SAE and MIL-Spec standards. Not FDA approved; not recommended for food-contact or ozone-heavy environments, or for direct sunlight exposure during storage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, or hydraulic system mechanics during fitting assembly or seal replacement. Depressurize and isolate the system completely before removing any existing fittings or seals. Lubricate the O-ring lightly with a compatible fluid before seating it in the boss recess to prevent rolling or pinching during assembly. Do not store O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N material 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: 0.924 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.116 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 912\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 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\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: ZMSCH70912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710382473522,"sku":"ZMSCH70912","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bed51e9f612b52a91cc9aef2512d5b1f.jpg?v=1788466222","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70912-o-ring-dash-912-nbr-70","provider":"Voomi Supply","version":"1.0","type":"link"}
