Hardness is rated at 90 durometer, placing it in the extra-hard category. This O-ring is designed for static and dynamic sealing applications where contact with petroleum-based fluids is expected. HVAC technicians, plumbers, and industrial maintenance professionals commonly use this size to seal hydraulic fittings, refrigerant service ports, fuel system connections, and general fluid-handling assemblies. The package contains 50 O-rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for applications involving petroleum products, hydraulic oils, fuels, and many common lubricants. Its operating temperature range of -40 to 250 degrees F makes it appropriate for both refrigeration and moderate-temperature hydraulic or fuel systems. Typical install scenarios include replacing worn seals on hydraulic cylinders, plumbing union connections, pump housings, and HVAC refrigerant-side fittings. It is not recommended for exposure to ozone, strong sunlight during storage, or applications involving ozone-generating equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (NBR) elastomer provides excellent resistance to petroleum products, fuels, and hydraulic oils\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating delivers strong compression set resistance and abrasion\/tear resistance\u003c\/li\u003e\n\u003cli\u003eTemperature range of -40 to 250 degrees F covers refrigeration, fuel, and light hydraulic service\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile; 0.1875-inch thickness conforms to standard Dash 325 dimensions\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eSold in a package of 50 for shop stock and service fleet use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products, hydraulic oils, and fuels per the manufacturer material data.

Depressurize and isolate the assembly before removing the existing O-ring. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Avoid storing unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone exposure degrades NBR compounds.\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: 325\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.5 inches (37.82 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.875 inches (47.62 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\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\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: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.98 pounds (package)\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: ZMSCH90325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695419982130,"sku":"ZMSCH90325","price":22.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32631cac69cc773d3f33c211570f93e1.jpg?v=1788334809","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90325-o-ring-dash-325-nbr-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
