It measures 17 inches inside diameter, 17.375 inches outside diameter, and 0.1875 inches (3\/16 inches) thick with a round cross section. Durometer hardness is rated at 70, placing it in the hard hardness category. The compound delivers excellent resistance to petroleum-based fluids along with strong compression set performance and good tear and abrasion resistance. Plumbers, HVAC technicians, and industrial maintenance professionals install this part in hydraulic, pneumatic, and fluid systems where a reliable face or radial seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and commercial systems that involve petroleum-based media, hydraulic fluids, and similar hydrocarbon-compatible fluids. Its temperature range spans -40 degrees F to 250 degrees F, making it appropriate for a broad range of service conditions. It is not recommended for exposure to ozone-generating equipment or direct sunlight during storage. The part is sold in a package quantity of 5 and meets SAE and MIL-Spec standards. Typical applications include pump seals, valve bodies, fittings, and manifold assemblies where a standard Dash 386 profile is called out.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products and hydrocarbon-based fluids\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness rating provides firm sealing with controlled compression set\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F suits a wide range of HVAC, plumbing, and hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard Dash 386 dimensional specifications per SAE and MIL-Spec\u003c\/li\u003e\n  \u003cli\u003eBlack color for visual confirmation during installation inspection\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 units, minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance seal for any application calling out a standard Dash 386 O-ring with Buna-N material.

Always depressurize and isolate the system before removing old seals or installing new ones. Lubricate the O-ring with a compatible fluid before seating to reduce the risk of twisting or tearing during assembly. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this degrades Buna-N compound over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 17.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\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\u003eDash Number\u003c\/strong\u003e: 386\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\u003eColor\u003c\/strong\u003e: Black\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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: ZMSCH70386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699936100658,"sku":"ZMSCH70386","price":21.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_e1019494-5fa3-4084-8fa0-e87fa5fdf907.jpg?v=1788383641","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70386-o-ring-dash-386-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
