It measures 0.313 inches inside diameter, 0.438 inches outside diameter, and 0.0625 inches thick with a round cross section. The compound is rated at 90 durometer, placing it in the extra-hard hardness range, which suits high-pressure sealing applications. The temperature range runs from -40 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and mechanical contractors install these rings wherever petroleum-based fluids or general hydraulic media are present.\u003c\/p\u003e\u003cp\u003eThis O-ring fits sealing grooves machined to Dash 011 dimensions per SAE and MIL-Spec standards. Typical applications include valve stems, fitting connections, pump housings, and refrigeration service fittings in residential and light commercial systems. The Buna-N elastomer compound offers strong resistance to petroleum products, good compression set performance, and solid tear and abrasion resistance, making it a standard choice across plumbing, HVAC, and general industrial maintenance work. These are sold in a package quantity of 100 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (nitrile butadiene rubber) elastomer — the most widely used O-ring compound for petroleum product compatibility\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating for high-pressure sealing environments\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec dimensional standards for Dash 011 cross section\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to tear and abrasion with reliable compression set performance\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 100 pieces per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and general hydraulic media.

Shut off fluid supply and relieve system pressure completely before disassembling any joint or fitting. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent tearing during assembly. Do not roll or twist the ring during installation, and inspect the groove for burrs or damage before reuse.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.313 inches (7.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.438 inches (11.12 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1.78 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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: ZMSCH90011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694677524786,"sku":"ZMSCH90011","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80cf2ed3312fbe1f69a0c5c7f34e65db.jpg?v=1788327051","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90011-o-ring-dash-011-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
