It measures 5.375 inches inside diameter, 5.75 inches outside diameter, and 0.1875 inches thick. Rated at 70 durometer hardness, this O-ring delivers reliable sealing performance across a wide service temperature range of -40 degrees F to 250 degrees F. It resists petroleum-based fluids and offers strong compression set, tear, and abrasion resistance. Licensed HVAC technicians, plumbers, and mechanical technicians reach for Buna-N O-rings when sealing hydraulic, pneumatic, and fluid systems where petroleum product exposure is expected.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and light commercial applications involving hydraulic systems, plumbing assemblies, pump housings, compressor fittings, and valve bodies where a Dash 356 size seal is required. Its petroleum-product compatibility makes it a common choice for fuel, oil, and hydraulic fluid circuits. The pack ships in a quantity of 5 units, making it practical for service technicians stocking common seal sizes. Store away from direct sunlight and sources of ozone such as electric motors to maintain elastomer integrity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (NBR) elastomer — the most widely used O-ring material for petroleum-product sealing\u003c\/li\u003e\n\u003cli\u003eDash 356 standard sizing: 5.375 inches ID, 5.75 inches OD, 0.1875 inches thick\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness rating — classified as hard, suitable for higher-pressure sealing applications\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent groove fit and uniform compression\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePack quantity of 5 per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products including hydraulic fluids, oils, and fuels.

Shut down the system and relieve all pressure before removing the old O-ring or seating the replacement. Lightly lubricate the O-ring with a compatible fluid or grease before installation to prevent tearing during seating. Do not install near active ozone sources or store in direct sunlight, as ozone and UV exposure degrade NBR elastomers over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 356\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 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: -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 Fluids\u003c\/strong\u003e: Petroleum products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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: 5\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: ZMSCH70356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701156217138,"sku":"ZMSCH70356","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_0c3ef0f7-c693-4aa6-a388-1913eb733c50.jpg?v=1788398967","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70356-o-ring-dash-356-nbr-5-375-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
