It measures 5.875 inches inside diameter by 6.375 inches outside diameter with a 0.25-inch cross-section thickness and a 90 Shore A durometer rating, placing it in the extra-hard hardness range. The round cross-section profile delivers reliable compression set performance and strong resistance to tearing and abrasion. This O-ring is rated for continuous service from -40 degrees F to 250 degrees F and is compatible with petroleum-based media. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals install this part in fluid and gas sealing applications where hydrocarbon resistance is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring suits static and low-cycle dynamic sealing applications in hydraulic systems, fuel systems, pneumatic fittings, and plumbing connections that contact petroleum-based fluids or oils. The Dash 436 sizing is a standard AS568 dimension used across a broad range of industrial, HVAC, and fluid-handling equipment. With SAE and MIL-Spec standards compliance, it is appropriate for both commercial and light industrial service environments. Sold in packages of 10, it is suited for stocking in shop or service truck inventory. This material should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone.\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\u003c\/li\u003e\n  \u003cli\u003e90 Shore A durometer (extra-hard) for high-compression sealing applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section, Dash 436 standard AS568 sizing\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eStrong tear and abrasion resistance with excellent compression set characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products including hydraulic oils, fuels, and lubricants.

Depressurize and isolate the system completely before removing the old O-ring. Inspect the groove and mating surfaces for scoring or contamination before seating the new ring. Avoid stretching the O-ring beyond its natural diameter during installation, and do not use petroleum-incompatible lubricants on the sealing surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.875 inches (5-7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.375 inches (6-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.25 inches (1\/4 inch) \/ 6.99 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 436\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: 90 Shore A (Extra Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 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: ZMSCH90436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703676141874,"sku":"ZMSCH90436","price":22.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_e8f03b6b-f3cf-4fb2-bb26-e2f82202873d.jpg?v=1788418009","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90436-o-ring-dash-436-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
