This O-ring measures 0.563 inches inside diameter and 0.813 inches outside diameter with a 0.125-inch cross-section thickness. The extra-hard 90-durometer hardness rating provides excellent compression set resistance, making it well suited for higher-pressure service points. Each package contains 50 O-rings. Installation is performed by licensed HVAC technicians, plumbers, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis Buna-N O-ring is a widely used sealing solution for systems that handle petroleum-based fluids, hydraulic oil, fuel, and similar media. The NBR compound delivers strong resistance to abrasion and tearing, and it maintains a reliable seal across a temperature range of -40 degrees F to 250 degrees F. It is appropriate for use in valve bodies, pump housings, fittings, and fluid line connections found in residential and light commercial mechanical systems. The black round cross-section profile seats cleanly in standard Dash 207 O-ring grooves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 207 standard sizing: 0.563 inches ID, 0.813 inches OD, 0.125 inches thick\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard Buna-N compound for high compression set resistance\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to petroleum products, hydraulic fluids, and similar media\u003c\/li\u003e\n\u003cli\u003eGood tear and abrasion resistance for dynamic sealing applications\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 50 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement O-ring for any application requiring a Dash 207 cross-section profile in Nitrile Butadiene Rubber.

Always depressurize and isolate the system before replacing O-rings, and confirm the groove dimensions match Dash 207 specifications before seating the ring. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as this degrades the NBR compound. Lubricate the O-ring with a compatible fluid during installation to reduce the risk of tearing during assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 207\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.563 inches (13.87 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.813 inches (20.65 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\u003eColor\u003c\/strong\u003e: Black\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: 0.35 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: ZMSCH90207\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693998473522,"sku":"ZMSCH90207","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_92f287c5-fa3e-460f-883c-1b87af997134.jpg?v=1788319485","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90207-o-ring-dash-207-nbr-90-duro-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
