Merit Brass XB187-32 Brass Pipe Union 2 in Class 125

Product Description

The MERIT BRASS XB187-32 is a Class 125 brass pipe union with female British Standard Pipe Taper (FBSPT) connections on both ends. This fitting is used to join two sections of threaded pipe in a way that allows future disconnection without cutting or disturbing the surrounding line. At 2 inches in size, it is suited for moderate-flow plumbing and fluid-handling systems where serviceable unions are required. Weighing 3.124 pounds, the fitting is made of brass, which offers good corrosion resistance in water and low-pressure steam service. Installation is performed by licensed plumbers or pipefitters working on threaded pipe systems.

This union is appropriate for residential and light commercial plumbing applications where FBSPT threaded connections are specified. Class 125 ratings are common in water supply, hydronic heating, and general fluid distribution lines. The FBSPT x FBSPT configuration makes this fitting compatible with standard tapered pipe threads on both sides of the union, allowing clean make-up and break-down of the joint during system maintenance or equipment replacement.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the applicable IPC or local plumbing code. Shut off and depressurize the supply line completely before disassembling or installing any union fitting. Apply an appropriate thread sealant or PTFE tape to all male threads before make-up. Do not over-tighten brass fittings, as the material is softer than ferrous pipe and can be damaged by excessive torque.
