It is used to join two sections of threaded black iron pipe in a way that allows future disconnection without cutting or unthreading the line. The black finish provides baseline rust resistance for indoor and dry-environment installations. National Pipe Threads (NPT) on both end connections create tighter seals than straight-thread designs. This fitting is sold individually and is installed by licensed plumbers and pipefitters working on gas distribution, steam, and hydronic systems.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial applications where a removable pipe connection is required. Typical scenarios include boiler room piping, gas appliance rough-in, and steam heating distribution lines. The ground joint seat design ensures a metal-to-metal seal at the union face, making it a reliable choice for systems where pipe sections must occasionally be broken apart for service or equipment replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMalleable black iron construction for strength and machinability under field conditions\u003c\/li\u003e\n\u003cli\u003eGround joint seat provides a metal-to-metal seal at the union face\u003c\/li\u003e\n\u003cli\u003eNational Pipe Threads (NPT) for tighter seals compared to straight-thread connections\u003c\/li\u003e\n\u003cli\u003eBlack finish for corrosion resistance in dry and indoor environments\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI B-16.39, ANSI B-16.14, and ANSI B-2.1 dimensional and thread standards\u003c\/li\u003e\n\u003cli\u003eMeets Federal Specification WW-U-531C for malleable iron unions Class 150\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-inch NPT black iron pipe systems, including gas, steam, and hydronic heating applications conforming to Class 150 malleable iron union specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the IFGC or IPC as appropriate for the service type. Shut off and depressurize the line completely before breaking or making any union connection. Apply thread sealant or PTFE tape rated for the intended service to all NPT connections before assembly. Do not overtighten the union nut beyond hand-tight plus a controlled turn, as excessive force can damage the ground joint seat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable black iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: National Pipe Thread (NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B-16.39, ANSI B-16.14, ANSI B-2.1, Fed.
