It measures 3.375 inches inside diameter, 3.625 inches outside diameter, and 0.125 inches thick with a round cross section. The 70 durometer hardness rating provides a firm, reliable seal under mechanical load. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is suited for high-temperature environments where standard nitrile or EPDM compounds fall short. It is sold in packages of 10 units.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in applications requiring resistance to petroleum-based fluids, hydraulic oils, fuels, and a wide range of chemical media. The Viton fluoroelastomer compound delivers low compression set, high temperature resistance, and low gas permeability, making it appropriate for vacuum service as well as pressurized systems. Licensed plumbers, HVAC technicians, and industrial mechanics routinely use Dash 237 O-rings in pump housings, valve bodies, filter housings, and compressor fittings where elevated operating temperatures and petroleum-fluid contact are both present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound with broad chemical compatibility\u003c\/li\u003e\n\u003cli\u003eRated -15 degrees F to 400 degrees F continuous operating range\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness for firm sealing under compression\u003c\/li\u003e\n\u003cli\u003eLow compression set for long-term seal integrity\u003c\/li\u003e\n\u003cli\u003eLow gas permeability suitable for vacuum service\u003c\/li\u003e\n\u003cli\u003eRound cross section per standard Dash 237 sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and a wide spectrum of chemical media.

Always depressurize and isolate the system before replacing any O-ring. Lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during assembly. Do not stretch the O-ring over sharp edges or threads, and inspect the gland groove for damage or debris before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 237\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\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: 70 durometer (Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: ZMSCV70237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697040818482,"sku":"ZMSCV70237","price":23.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dd96ab3f9d94c2ca73982f53e59ee12.jpg?v=1788348770","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70237-viton-o-ring-dash-237","provider":"Voomi Supply","version":"1.0","type":"link"}
