It measures 3.38 inches inside diameter and 3.63 inches outside diameter with a 0.125-inch (1\/8 inch) round cross section. The compound is Nitrile Butadiene Rubber (NBR) with a Shore A hardness of 70, rated for continuous service from -40 degrees F to 275 degrees F. This combination of temperature range and NBR chemistry makes it well suited for oil, fuel, and water service in mechanical assemblies. Licensed trades and maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring fits groove-seated sealing applications where a Dash 237 standard O-ring is specified. Typical installations include pump housings, valve bodies, pipe unions, manifold covers, and filter housings in residential and commercial systems. The 3.38-inch ID size is common in mid-to-large diameter fittings and equipment ports. NBR is compatible with petroleum-based oils, hydraulic fluids, water, and many refrigerants, making it a versatile choice across HVAC, plumbing, pool, and light industrial service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 237 standard sizing for direct drop-in replacement in groove-seated applications\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (NBR) compound resists petroleum oils, hydraulic fluids, and water\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 provides firm sealing compression without excessive deformation\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 275 degrees F covers most HVAC and plumbing service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross section ensures even groove contact and consistent seal integrity\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds for easy handling and storage in field service kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 237 O-ring replacement for groove-seated seal applications requiring a 3.38-inch ID NBR O-ring in HVAC, plumbing, pool, and industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and isolate the system before removing the old O-ring, and clean the groove of debris, old lubricant, and corrosion before seating the new ring. Apply a light coat of compatible lubricant to the O-ring to reduce installation friction and prevent tearing during assembly. Do not twist or roll the O-ring during installation, as this can compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 237\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70\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: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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: ZBD9993-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717363958066,"sku":"ZBD9993-10","price":34.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e9585d3468c8ee19bef2c669d7198d9.jpg?v=1788539184","url":"https:\/\/voomisupply.com\/products\/value-collection-zbd9993-10-o-ring-dash-237-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
