It measures 1 inch inside diameter, 1.188 inches outside diameter, and 0.094 inches thick with a round cross section. Shore hardness is rated at 90 durometer, classifying it as extra hard. The operating temperature range spans -40 degrees F to 250 degrees F. Buna-N is the most widely used O-ring elastomer in the trade and provides excellent resistance to petroleum-based fluids, making it a go-to choice for HVAC technicians, plumbers, and fluid-power mechanics performing routine maintenance or system assembly.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel-handling lines, and general plumbing connections where petroleum product exposure is expected. It is commonly installed in valve bodies, pump housings, cylinder heads, and pipe fittings. The 50-piece packaging makes it practical for service vans and shop inventory. It meets SAE and MIL-Spec standards, covering a broad range of residential and commercial service applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating for high-compression sealing performance\u003c\/li\u003e\n  \u003cli\u003eTemperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 120 designation for standard-size fitment\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eBlack color; 50-piece package quantity for shop or van stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based products and fluids.

De-energize and depressurize the system fully before removing the old O-ring or installing a new one. Lightly lubricate the O-ring with a compatible fluid or grease before seating to reduce the risk of tearing during assembly. Do not store O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this degrades elastomer integrity over time.\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: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.1880 inches (30.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (2.62 mm)\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: 90 Shore A (Extra 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 Material\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 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: ZMSCH90120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702050062642,"sku":"ZMSCH90120","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_729d62dc-42f1-4f95-a668-ca0e8730ad39.jpg?v=1788408602","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90120-o-ring-dash-120-nbr-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
