Merit Brass C110-04 Brass Pipe Cross 1/4 in Fnpt Class 125

Product Description

The MERIT BRASS C110-04 is a Class 125 brass pipe cross fitting designed for four-way pipe connections in pressurized fluid and gas piping systems. All four ports feature female national pipe taper (FNPT) threads, allowing direct connection to male-threaded pipe ends without adapters. Weighing 0.15 pounds, this compact quarter-inch fitting suits tight installations where space is limited. It is a standard choice for licensed plumbers, pipefitters, and HVAC technicians working on branch distribution lines in both residential and light commercial applications.

This fitting is suited for use in residential and light commercial piping systems where a four-way branch is required at a 1/4-inch pipe size. Typical installations include instrument air lines, gas distribution manifolds, compressed air systems, and low-pressure fluid circuits. Its all-FNPT configuration makes it straightforward to integrate into existing threaded pipe runs. Plumbers and pipefitters install this type of cross fitting when splitting a single supply line into multiple branch directions within the same plane.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or local jurisdiction requirements. Shut off and depressurize the pipe system fully before disassembling any existing fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-tighten, as brass fittings can crack under excessive torque.
