It measures 16 inches inside diameter, 21 inches outside diameter, and 2.5 inches thick with a round cross section. The material carries a Shore A hardness of 70, placing it in the hard durometer range. Its working temperature range spans -40 degrees F to 250 degrees F, making it suitable for a wide variety of service conditions. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used wherever a large-diameter NBR seal is required — common applications include pump flanges, valve bonnets, large pipe unions, industrial equipment housings, and pool or water treatment system fittings. Its Buna-N compound provides excellent resistance to petroleum-based fluids, hydraulic oils, and lubricants, making it a standard choice in oil and gas, refrigeration, and general mechanical service. Not recommended for exposure to ozone, sunlight, or aromatic solvents. Sold in a package quantity of 100.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) elastomer — the most widely used O-ring material for petroleum and hydraulic fluid compatibility\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for reliable compression set and sealing force\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard groove seating\u003c\/li\u003e\n  \u003cli\u003eExcellent tear and abrasion resistance for dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, and lubricants.

Shut off and depressurize the system and drain any fluid before replacing seals. Lubricate the O-ring with a compatible fluid during installation to prevent tearing or twisting in the groove. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this degrades NBR elastomers.\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\u003eInside Diameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2.5 inches\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: 70 Shore A (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 Fluids\u003c\/strong\u003e: Petroleum Products, Hydraulic Oils, Lubricants\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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: 100\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: ZMSCH2.5X16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715650257202,"sku":"ZMSCH2.5X16","price":20.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a14b0ff3c13fb903eac416d44db136a0.jpg?v=1788516784","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch2-5x16-o-ring-16in-id-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
