Merit Brass XB106-20 Brass Pipe Tee 1-1/4 in Fbspt Class 125

Product Description

The MERIT BRASS XB106-20 is a Class 125 brass pipe tee designed for threaded piping systems in plumbing, HVAC hydronic loops, and general industrial piping applications. All three ports feature Female British Standard Pipe Taper (FBSPT) threads in a 1-1/4 inch size, allowing a branch connection in line with the run pipe. The tee weighs 1.18 pounds and is manufactured from brass, offering good corrosion resistance in water, steam, and light gas service. Licensed plumbers and pipefitters are the primary installers of this fitting class.

This tee is suited for residential and light commercial piping applications where a threaded branch connection is required at a 1-1/4 inch pipe size. Typical install scenarios include domestic water distribution, hydronic heating systems, compressed air lines, and low-pressure gas piping where Class 125 pressure ratings are acceptable. Its equal-end FBSPT configuration makes it a standard run-and-branch fitting without requiring reducers at any port.

Key Features

• Class 125 pressure rating suitable for water, steam, and low-pressure gas service
• All three ends are FBSPT threaded for straightforward male-threaded pipe engagement
• 1-1/4 inch fitting size fits standard Schedule 40 pipe of the same nominal diameter
• Brass construction provides corrosion resistance and reliable sealing with thread sealant or tape
• Equal tee configuration — run and branch ports are all the same size, no reducers needed

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded brass piping systems using 1-1/4 inch nominal pipe size with FBSPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off system pressure and drain the line before removing or installing any threaded fitting. Apply an approved thread sealant compound or PTFE tape to all male threads before engagement — do not apply sealant to the female ports on this tee. Tighten to hand-tight plus the appropriate number of turns per pipe trade practice; do not use excessive force that could crack the fitting body.
