Merit Brass C106-06 Brass Pipe Tee 3/8 in Fnpt Class 125

Product Description

The MERIT BRASS C106-06 is a Class 125 brass pipe tee designed for threaded pipe assemblies in plumbing, HVAC, and general fluid-handling systems. The fitting connects three pipe runs at a branch point using female National Pipe Taper (FNPT) threads on all three ends. At 3/8-inch nominal pipe size, this tee suits smaller-diameter runs where a threaded branch connection is required. Weighing 0.2 pounds, it is compact and well-suited for installations where space is limited. Licensed plumbers and pipefitters are the primary installers, though experienced service technicians working on hydronic or refrigerant-adjacent piping regularly work with fittings of this type.

This tee is appropriate for residential and light commercial plumbing and HVAC applications where Class 125 brass threaded fittings meet system pressure requirements. Typical uses include water distribution branch lines, compressed-air distribution, and low-pressure gas piping where local codes permit brass threaded fittings. The 3/8-inch FNPT x FNPT x FNPT configuration accepts standard tapered male-threaded pipe ends on all ports.

Key Features

• All three ports feature FNPT (Female National Pipe Taper) threads for a standard tapered thread seal
• Class 125 pressure rating suitable for low- to moderate-pressure service
• 3/8-inch nominal pipe size fits standard 3/8-inch male-threaded pipe or fittings
• Brass construction offers corrosion resistance in water and air service
• Tee configuration allows a 90-degree branch off a straight pipe run

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/8-inch FNPT threaded pipe systems rated for Class 125 service.

Installation Notes

Installation of threaded brass fittings is typically performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to the male threads before makeup — do not apply sealant to female threads. Hand-tighten first, then use a pipe wrench for final makeup; avoid overtightening, which can crack brass fittings.
