It measures 0.438 inches inside diameter, 0.625 inches outside diameter, and 0.0937 inches thick. The X-profile cross section — also called a quattro or four-lobed profile — provides improved sealing stability and reduced rolling in the gland compared to standard round-section o-rings. This part is suited for static and dynamic sealing applications in fluid and pneumatic systems across HVAC, plumbing, and general industrial maintenance.\u003c\/p\u003e\n\u003cp\u003eThis o-ring fits sealing applications that require a Dash 111 size in the inch measurement system. The NBR compound handles petroleum-based oils, fuels, and water-based fluids well, making it a common choice in refrigeration service valves, hydraulic fittings, plumbing shutoff assemblies, and pneumatic tool connections. The rated temperature range of -30 degrees F to 250 degrees F covers the majority of residential and light commercial service conditions. Sold in a package of 100, it is appropriate for shops and field technicians who replace o-rings in volume. Note that this part is not FDA approved and should not be used in food-grade or potable-water-contact applications without verifying local code compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eX-profile (quattro) cross section resists gland rolling and improves seal stability over standard round o-rings\u003c\/li\u003e\n  \u003cli\u003eNBR compound provides strong resistance to petroleum oils, hydraulic fluids, and water-based media\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer — hard rating — suitable for higher-pressure sealing applications\u003c\/li\u003e\n  \u003cli\u003eRated from -30 degrees F to 250 degrees F for broad service temperature coverage\u003c\/li\u003e\n  \u003cli\u003eDash 111 size: 0.438 inches ID, 0.625 inches OD, 0.0937 inches thick\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for shop stock and high-volume field service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 111 inch-series o-ring replacement for static and dynamic sealing applications in HVAC service valves, plumbing fittings, pneumatic assemblies, and hydraulic connections where an X-profile NBR compound is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or maintenance mechanics during valve service or fitting assembly. Always depressurize and isolate the system before removing the existing o-ring, and verify the gland dimensions match Dash 111 specifications before installation. Apply a compatible o-ring lubricant sparingly to ease installation and avoid pinching or twisting the cross section in the groove. Do not use petroleum-based lubricants with incompatible elastomers, and confirm the fluid media is compatible with NBR before installation.\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 (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 111\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: X-Profile (Quattro)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.438 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurometer Shore A\u003c\/strong\u003e: 70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -30 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\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: ZMSCQH70111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720826388786,"sku":"ZMSCQH70111","price":20.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/869a365fc81f8c97dc13dcb5ffc2933b.jpg?v=1788569644","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscqh70111-o-ring-dash-111-nbr-70","provider":"Voomi Supply","version":"1.0","type":"link"}
