It features a 14.475-inch inside diameter, a 15-inch outside diameter, and a 0.25-inch cross-section thickness. Rated at 90 durometer (extra hard), this O-ring delivers firm compression set resistance along with strong tear and abrasion resistance. Its Buna-N compound provides excellent resistance to petroleum-based fluids, making it a reliable sealing solution across a wide range of trade and industrial service environments. Licensed HVAC techs, plumbers, and industrial service professionals install this type of seal regularly in fluid and gas handling systems.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications where contact with petroleum products, hydraulic fluids, or mineral oils is expected. Its operating temperature range of -40 to 250 degrees F makes it appropriate for both refrigeration-adjacent and higher-heat plumbing or mechanical service scenarios. The extra-hard 90 durometer rating is well matched to high-pressure or high-extrusion-risk installations. It meets SAE and MIL-Spec standards and ships in a package quantity of 2.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating for high-pressure and extrusion-resistant sealing\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 to 250 degrees F for broad service temperature coverage\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile, Dash 458 standard sizing\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eTear and abrasion resistant; good compression set characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic fluids, and mineral oil-based media.

Always depressurize and isolate the system before removing or installing O-rings. Inspect the sealing groove for burrs, corrosion, or wear before seating the new O-ring. Avoid twisting the O-ring during installation, and apply a compatible lubricant to ease seating and reduce the risk of damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 14.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches (6.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 458\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: 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 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.17 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: ZMSCH90458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689555329330,"sku":"ZMSCH90458","price":16.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/858d3d0f148110e91694b5a394a0e628.jpg?v=1788261284","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90458-dash-458-nbr-o-ring-90d","provider":"Voomi Supply","version":"1.0","type":"link"}
