It measures 4.75 inches inside diameter, 5.125 inches outside diameter, and 0.1875 inches in cross-section thickness, with a round cross-section profile. Rated at 90 durometer (extra hard), it delivers excellent resistance to petroleum-based fluids along with strong compression set characteristics and good tear and abrasion resistance. The operating temperature range spans -40 degrees F to 250 degrees F. Installation is performed by maintenance technicians, millwrights, and hydraulic system specialists across a wide range of industrial and fluid-handling applications.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for static and dynamic sealing in hydraulic cylinders, pneumatic assemblies, pumps, valves, and pipe fittings where petroleum-product compatibility is required. The Buna-N compound makes it appropriate for use with oils, fuels, and hydraulic fluids commonly encountered in industrial machinery, HVAC equipment, and fluid-power systems. The Dash 351 designation conforms to standard O-ring sizing, making it a straightforward replacement in any application calling for that dash number. Sold in a package quantity of 10 per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating for high-compression sealing applications\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F for broad service compatibility\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile conforms to SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eGood tear and abrasion resistance for dynamic sealing environments\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 10 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products including oils, fuels, and hydraulic fluids.

Before servicing any assembly, depressurize the system completely and isolate all fluid or pneumatic supply lines. Lubricate the O-ring with a compatible fluid or grease prior to seating to prevent pinching or tearing during installation. Inspect the mating groove for burrs, corrosion, or dimensional damage before fitting the new seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 351\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.75 inches (120.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.125 inches (130.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (5.33 mm)\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: 90 durometer (Extra 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 Material\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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: 1.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH90351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692108153138,"sku":"ZMSCH90351","price":16.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/580b202075d50328b4309fd66c1e7e8f.jpg?v=1788293219","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90351-o-ring-dash-351-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
