The black iron finish provides baseline corrosion resistance in dry or low-moisture environments. National Pipe Threads (NPT) on both ends create tapered, pressure-assisted seals tighter than straight-thread connections. This Class 150 union is built to ANSI B-16.39 dimensional and performance standards and is a standard fitting for licensed plumbers and pipefitters working on gas, steam, or water distribution systems.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial piping applications where a serviceable break point is needed in a threaded black iron pipe system. Typical installations include gas supply lines, low-pressure steam systems, and general plumbing distribution. The ground joint design allows the union to seat and seal without a separate gasket, making it a reliable choice for repeated service access points in mechanical rooms and utility spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch NPT ground joint design seats without a separate gasket\u003c\/li\u003e\n\u003cli\u003eMalleable black iron construction provides ductility and impact resistance\u003c\/li\u003e\n\u003cli\u003eBlack finish offers baseline rust resistance in dry service conditions\u003c\/li\u003e\n\u003cli\u003eClass 150 pressure rating per ANSI B-16.39\u003c\/li\u003e\n\u003cli\u003eTapered NPT threads conform to ANSI B-2.1 for pressure-tight seals\u003c\/li\u003e\n\u003cli\u003eMeets Federal Specification WW-U-531C and ANSI B-16.14 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for 3\/8 inch threaded black iron pipe systems conforming to ANSI B-16.14 and ANSI B-16.39 standards.\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 International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off and depressurize the pipe system completely before disassembling or installing any union. Apply an approved pipe thread sealant or PTFE tape to the NPT threads before assembly; do not apply sealant to the ground joint mating faces. Hand-tighten first, then use a pipe wrench to bring the union nut to full engagement without over-stressing the fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT (National Pipe Thread, tapered)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: Ground joint\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\u003ePressure Class\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: Fed.
