Built to Class 300 standards, it carries a liquid and gas pressure rating of 1500 psi, making it suitable for demanding service conditions. The black finish is applied over malleable iron construction, providing corrosion resistance appropriate for general-purpose applications. This fitting is typically installed by licensed plumbers and pipefitters working on ferrous pipe systems where a break-apart union connection is required for future serviceability.\u003c\/p\u003e\n\u003cp\u003eThis union is used in residential and light commercial gas piping, compressed air lines, and water distribution systems where threaded malleable iron fittings are specified. The 3\/4-inch size fits standard NPT threaded pipe of the same nominal diameter. Its Class 300 pressure rating makes it appropriate for applications where pressure demands exceed the limitations of standard Class 150 fittings. It is sold in a package quantity of 5 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and durability in ferrous pipe systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish for general-purpose plumbing and gas piping applications\u003c\/li\u003e\n  \u003cli\u003eClass 300 rating with 1500 psi liquid and gas pressure capacity\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch threaded end connections for standard NPT pipe\u003c\/li\u003e\n  \u003cli\u003eUnion design allows pipe assembly to be disconnected without cutting\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3\/4-inch threaded malleable iron pipe systems requiring a Class 300 union connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IFGC requirements for gas service applications. Shut off all gas or fluid supply and depressurize the line completely before disassembling or installing any union fitting. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten, as malleable iron threads can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Threaded (NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 1500 psi (liquid and gas)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175303\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: 13584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716933583154,"sku":"13584","price":135.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6ebf7ffcfb45a459ea90b63113f1cd3.jpg?v=1788533566","url":"https:\/\/voomisupply.com\/products\/value-collection-13584-black-iron-union-3-4-in-threaded-class-300","provider":"Voomi Supply","version":"1.0","type":"link"}
