It features a 14-inch inside diameter, a 14.375-inch outside diameter, and a 3\/16-inch (0.1875-inch) round cross section. Shore hardness is rated at 70, placing it in the hard hardness range. This O-ring delivers excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. It is a standard sealing component installed by plumbers, pipefitters, hydraulic technicians, and mechanical trade professionals across a wide range of industrial and commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications where contact with petroleum products, oils, fuels, or hydraulic fluids is expected. Its large diameter makes it appropriate for pipe flanges, pump housings, valve bonnets, and large-bore cylinder end caps in commercial, industrial, and heavy mechanical service environments. Operating temperature range spans -40 degrees F to 250 degrees F, making it viable across most North American climate and process conditions. This item is sold in a package quantity of 5.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003eDash 383 standard sizing: 14-inch ID, 14.375-inch OD, 0.1875-inch cross section thickness\u003c\/li\u003e\n  \u003cli\u003eShore hardness of 70 (hard rating) for reliable compression and sealing force\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent groove seating and uniform load distribution\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, fuels, and related fluids.

Before installation, depressurize and drain the system completely and confirm the groove dimensions match the Dash 383 cross section. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to avoid nicking or rolling during assembly. Do not use petroleum-incompatible lubricants or expose the O-ring to ozone-generating equipment during storage or installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 383\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 14 inches (14.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 14-3\/8 inches (14.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches (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 Shore (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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Fluids\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: 5\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: ZMSCH70383\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692221071666,"sku":"ZMSCH70383","price":16.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_032ce047-dec2-4da9-bd71-497a78cbf403.jpg?v=1788294781","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70383-o-ring-dash-383-nitrile-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
