The extra-hard Shore A rating delivers firm sealing compression in high-load or high-vibration environments. With a rated temperature range of -40 to 250 degrees F, this O-ring handles both low-temperature cold-weather service and the elevated heat found in hydraulic, pneumatic, fuel, and fluid-handling systems. It is sold in a package of 5 pieces. Plumbers, HVAC technicians, and mechanical maintenance trades install NBR O-rings as static face seals, fitting seals, and valve-body seals across a wide range of service equipment.\u003c\/p\u003e\n\u003cp\u003eNBR O-rings in the Dash 8-425 size are commonly used in residential and commercial plumbing connections, HVAC refrigerant-side and hydronic fittings, pool and spa equipment unions, and general industrial fluid-line assemblies. The 4.5-inch inside diameter suits large-bore pipe fittings, pump flanges, and valve bodies where a reliable, chemically resistant seal is required. This size is frequently encountered in pool equipment manifolds, large gate valves, and circulating pump covers in both light commercial and residential applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (NBR) construction resists petroleum-based oils, fuels, hydraulic fluids, and water\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating provides firm, reliable compression in high-load static seal applications\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range from -40 to 250 degrees F suits cold-climate and elevated-heat installations\u003c\/li\u003e\n  \u003cli\u003eRectangular cross-section profile for Dash 8-425 fitment in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003ePackaged in a quantity of 5, suitable for service kits, stock replenishment, or multi-unit repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service seal for large-bore fittings, valves, pump flanges, and fluid-line components requiring a Dash 8-425 O-ring with a 4.5-inch inside diameter and 90-durometer NBR material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlumbers and mechanical technicians should depressurize and drain the system before replacing any O-ring seal. Clean the mating groove and sealing surfaces to remove debris, old seal material, and corrosion before seating the new O-ring. Apply a compatible, system-appropriate lubricant to the O-ring to ease installation and prevent tearing. Verify that the groove dimensions match the Dash 8-425 cross section to ensure proper compression and sealing performance.\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 (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 8-425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Nominal)\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Decimal)\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Rectangle\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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCHB90425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714137522482,"sku":"ZMSCHB90425","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbbcceebcc98f31c0d76bce29370f44a_83ca4793-b19b-423b-8899-484859e148c2.jpg?v=1788496738","url":"https:\/\/voomisupply.com\/products\/value-collection-zmschb90425-o-ring-4-5-in-id-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
