Rated at 70 Shore A hardness, it delivers reliable sealing performance in applications involving petroleum-based fluids. Operating temperature range spans -40 degrees F to 250 degrees F, making it suitable for a broad range of service conditions. Licensed trades and maintenance professionals install this O-ring in hydraulic, pneumatic, and fluid-handling systems where a dependable static or dynamic face seal is required. Each package contains 2 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis Dash 336 O-ring is well suited for use in HVAC refrigerant-adjacent assemblies, plumbing fittings, hydraulic manifolds, and general industrial fluid systems where petroleum product exposure is expected. Its Buna-N elastomer construction provides excellent resistance to oils, fuels, and petroleum-based lubricants, making it a go-to sealing solution for technicians servicing pumps, valves, compressors, and pipe fittings in both residential and commercial settings. The round cross-section profile seats cleanly into standard Dash 336 O-ring grooves without special tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) elastomer — the most widely used O-ring material for petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for reliable compression set and sealing under pressure\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eExcellent tear and abrasion resistance extends service life in dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile fits standard Dash 336 grooves\u003c\/li\u003e\n  \u003cli\u003ePackage of 2 O-rings per unit; sold in single-package minimum order quantity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in applications compatible with petroleum products and Buna-N elastomers.

Always depressurize and isolate the system before removing the old O-ring. Lightly lubricate the O-ring with a compatible petroleum-based or system-appropriate lubricant before seating to prevent pinching or tearing during installation. Inspect the groove for nicks or debris before installing the new ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\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: Buna-N (Nitrile Butadiene Rubber)\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\u003eDash Number\u003c\/strong\u003e: 336\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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 O-rings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 6.24 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 inches L x 4 inches W x 1 inch H\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: ZMSCH70MD336\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711901237554,"sku":"ZMSCH70MD336","price":16.24,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_ffd23a3c-1b6b-4676-a949-9a304dffcb97.jpg?v=1788481143","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md336-o-ring-dash-336-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
