It measures 1.355 inches inside diameter, 1.587 inches outside diameter, and 0.116 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring delivers excellent compression set resistance along with strong tear and abrasion resistance. It is compatible with petroleum-based fluids and performs across a temperature range of -40 to 250 degrees F. Licensed trades and maintenance professionals install this seal in hydraulic, pneumatic, and fluid-handling assemblies where a firm, reliable seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and commercial mechanical systems involving petroleum-product fluid circuits, including hydraulic lines, fuel systems, and pneumatic fittings. Its Buna-N construction makes it a standard choice in HVAC, plumbing, and industrial maintenance applications where exposure to oils, fuels, and lubricants is expected. The part ships in a package quantity of 100, making it practical for shop stock, service vans, or bench-level repair work. It should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone exposure degrades NBR compounds over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — most widely used O-ring elastomer for petroleum-fluid compatibility\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating for high-compression-load sealing applications\u003c\/li\u003e\n\u003cli\u003eDash 918 standard sizing: 1.355 inches ID, 1.587 inches OD, 0.116 inches cross section\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to compression set, tearing, and abrasion\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 products including oils, fuels, and hydraulic fluids.

Always depressurize and isolate the fluid circuit before removing or installing any O-ring seal. Inspect the seating groove for burrs or contamination before installing a new ring. Avoid stretching the O-ring beyond the minimum necessary to seat it, and do not expose it to ozone-generating equipment during storage or service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.355 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.587 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.116 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 918\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: 90 Durometer (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 Fluids\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: 0.95 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: ZMSCH90918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690351231282,"sku":"ZMSCH90918","price":20.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_0af8ffc3-5398-44af-87ed-4d3634b69f49.jpg?v=1788269272","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90918-o-ring-dash-918-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
