Merit Brass XNL187-24 Brass Pipe Union 1-1/2 in Fnpt 125 Lb

Product Description

The MERIT BRASS XNL187-24 is a 1-1/2 inch nominal brass pipe union with female NPT (FNPT) end connections rated at 125 lb. Unions allow piping systems to be broken apart and reassembled without cutting or threading new pipe, making them a standard component in any system that requires periodic service access. This fitting features a rough brass finish and is manufactured as an import product. It is installed by licensed plumbers and pipefitters working on water, gas distribution, and general fluid-handling systems where a removable, leak-free joint is required.

This union is suited for residential and light commercial plumbing and gas piping applications where 1-1/2 inch threaded connections are specified. The FNPT end style threads directly onto male NPT pipe ends, providing a secure mechanical and pressure-rated seal. The 125 lb pressure class makes it appropriate for standard low-to-medium pressure service lines. Typical installation scenarios include boiler piping, water supply distribution, and other systems requiring periodic disconnection for equipment servicing or replacement.

• 125 lb pressure class rated for standard low-to-medium pressure service

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the supply line and verify the system is fully drained before disassembling or installing any union fitting. Apply thread sealant or PTFE tape to male NPT threads before assembly and tighten to hand-snug plus the appropriate number of turns per standard pipe fitting practice. Do not over-torque brass fittings, as the material is softer than ferrous alternatives and threads can be damaged.
