It features a round cross-section profile and a Shore A hardness rating of 70, placing it in the hard durometer range. This O-ring is used to create static and dynamic seals in fluid and pneumatic systems across plumbing, hydraulic, and mechanical applications. Plumbers, pipefitters, and maintenance technicians install these as replacement seals in valves, fittings, pumps, and fluid connectors where petroleum-based media are present. Each package contains 50 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in systems handling petroleum products, hydraulic oils, fuels, and related fluids. Its operating temperature range of -40 degrees F to 250 degrees F makes it appropriate for both refrigerated and moderately elevated-temperature environments. Typical install scenarios include valve body sealing, pump shaft seals, threaded fitting interfaces, and cylinder end caps in residential and light commercial plumbing and hydraulic systems. Buna-N is the most widely specified O-ring elastomer in general trade use and is stocked as a standard seal in service shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) material with excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for reliable compression set performance in dynamic and static sealing applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile — 25 mm ID, 31 mm OD, 3 mm thickness\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold in a package of 50 for shop and field stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, and fuels.

Not FDA approved; not recommended for food-contact or ozone-exposure environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by plumbers, pipefitters, or hydraulic technicians during valve, pump, or fitting service. Depressurize and drain the system fully before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Store unused O-rings away from direct sunlight, ozone sources, and electrical equipment that may generate ozone, as exposure will degrade the elastomer over time.\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 31 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70 (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\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\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: ZMSCH3X25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714639790386,"sku":"ZMSCH3X25","price":19.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_06bcd97f-6a26-4740-8905-9848c0c66c0d.jpg?v=1788504275","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch3x25-o-ring-25mm-id-nitrile-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
