It measures 2.5 inches inside diameter, 2.75 inches outside diameter, and 0.125 inches thick, with a round cross-section and an extra-hard 90 durometer rating. The higher durometer makes it well suited for applications where extrusion resistance and dimensional stability under pressure are priorities. Rated for service from -40 to 250 degrees F, this O-ring delivers reliable sealing across a broad temperature range. Sold in a package of 50.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used in hydraulic systems, pneumatic assemblies, fluid connectors, pump housings, valve stems, and plumbing fittings where petroleum-based fluid compatibility is required. The Buna-N compound provides excellent resistance to petroleum products, oils, fuels, and hydraulic fluids, making it a standard choice for HVAC refrigerant circuits using mineral oil, plumbing compression fittings, and general industrial fluid systems. The Dash 230 designation is an industry-standard AS568 size, allowing direct cross-reference with OEM seal kits and maintenance catalogs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (Buna-N) compound with excellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating for improved extrusion resistance in higher-pressure applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 to 250 degrees F for wide service flexibility\u003c\/li\u003e\n  \u003cli\u003eAS568 Dash 230 standard sizing allows direct cross-reference with OEM and aftermarket seal kits\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage of 50 units supports maintenance stock and repair kit assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, and fuels.

Always depressurize and isolate the system before replacing any O-ring seal. Lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during assembly. Inspect the gland seat for nicks, burrs, or corrosion that could compromise the seal before installing a new ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 230\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.5 inches (63.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.75 inches (69.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 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 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, hydraulic oils, fuels\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.36 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: ZMSCH90230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716262822194,"sku":"ZMSCH90230","price":18.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_4dac3735-0bc5-44c9-9841-dd1e41e37614.jpg?v=1788523740","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90230-o-ring-dash-230-nbr-90-duro-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
