It measures 1.188 inches inside diameter, 1.375 inches outside diameter, and 0.094 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. The temperature range spans -40 to 250 degrees F, making it suitable for a broad range of service conditions. Licensed plumbers, HVAC technicians, and pipefitters install these in hydraulic, pneumatic, and fluid system assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic oils, and fuels. Its Buna-N compound provides excellent resistance to petroleum products, which makes it a common choice in HVAC refrigerant line fittings, plumbing valves, hydraulic cylinders, and pump assemblies. The Dash 123 designation follows the AS568 standard sizing system, allowing straightforward cross-referencing across manufacturers and applications. It is sold in a package quantity of 50, well suited to contractors and service shops that maintain O-ring assortments for field repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating for high-compression sealing applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eDash 123 sizing per AS568 standard: 1.188 inches ID x 1.375 inches OD x 0.094 inches thick\u003c\/li\u003e\n  \u003cli\u003eRound cross-section with strong tear and abrasion resistance\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 products, hydraulic oils, and fuels.

Depressurize and drain the system fully before replacing any O-ring to prevent fluid release or injury. Lightly lubricate the O-ring with a compatible fluid prior to seating to reduce installation stress and prevent tearing. Inspect the mating groove for wear, burrs, or contamination before installing the new seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.188 inches (29.82 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.375 inches (34.92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 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\u003eDash Number\u003c\/strong\u003e: 123\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH90123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700939292978,"sku":"ZMSCH90123","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_12b40070-ba3d-4d0e-8c20-d83b82f54c09.jpg?v=1788395608","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90123-o-ring-dash-123-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
