It measures 3.375 inches inside diameter, 3.625 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers strong compression set resistance along with excellent tear and abrasion resistance. It is sold in a package of 50 units and suits plumbing, HVAC, and industrial fluid-handling applications where petroleum-based media are present. Licensed tradespeople and maintenance professionals install these as static or dynamic seals in fittings, valves, pumps, and manifolds.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and commercial systems handling petroleum-based fluids, oils, fuels, and hydraulic media. Its operating temperature range spans -40 degrees F to 250 degrees F, making it appropriate for both refrigeration-adjacent piping and hot-fluid circuits. Typical installations include valve bodies, pipe unions, pump housings, and hydraulic fittings where a reliable, compression-style face or radial seal is required. The 50-piece pack supports service shops and field technicians who carry common seal sizes as stock items.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides a firm, reliable seal under compression\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits a wide range of fluid-handling systems\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 237 standard sizing for straightforward drop-in replacement\u003c\/li\u003e\n  \u003cli\u003eStrong tear and abrasion resistance extends service life in dynamic and static groove applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards; sold in a 50-piece package for service-stock use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service-stock seal for any application requiring a Dash 237 O-ring groove.

Always depressurize and drain the system before replacing any seal. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating it in the groove to prevent pinching or tearing during assembly. Inspect the groove for burrs or damage before installation, and never reuse a removed O-ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eDash Number\u003c\/strong\u003e: 237\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\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: 0.02 pounds\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: ZMSCH70237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689029992754,"sku":"ZMSCH70237","price":15.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2215427b4e8ff7e8e5db91aa139a0a2c.jpg?v=1788254080","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70237-o-ring-dash-237-buna-n-pack-of-50","provider":"Voomi Supply","version":"1.0","type":"link"}
