Merit Brass NL106-06 Straight Pipe Tee 3/8 in Fnpt 125 Lb

Product Description

The MERIT BRASS NL106-06 is a straight pipe tee fitting designed for threaded pipe systems in residential and commercial plumbing, gas distribution, and industrial fluid handling applications. It carries a 125 lb pressure rating and features female national pipe taper (FNPT) end connections on all three ports. Constructed from solid brass with a rough finish, this tee provides reliable performance in low- to medium-pressure installations. It is sized at 3/8 inch nominal and is domestically manufactured, making it a standard-duty choice for licensed plumbers and pipefitters working on code-compliant systems.

This fitting is suited for use in residential water supply lines, commercial plumbing rough-in work, compressed air distribution, and light industrial fluid systems where FNPT threaded connections are required. The 3/8 inch nominal size makes it a common selection for branch connections in supply lines serving fixtures, valves, and instrumentation. Licensed plumbers and gas fitters install this tee in both new construction and retrofit applications requiring a durable brass threaded split.

Key Features

• 125 lb pressure rating suitable for standard residential and commercial service
• FNPT end style on all three ports for compatibility with standard threaded pipe
• 3/8 inch nominal sizing fits common supply and branch line applications
• Solid brass construction provides corrosion resistance in water and gas service
• Rough finish for use where a finished appearance is not required
• Domestically manufactured for projects with domestic-content requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 3/8 inch nominal FNPT threaded pipe systems rated at 125 lb or less.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Power down or shut off the relevant fluid or gas supply before cutting into any existing line. Apply an approved thread sealant or PTFE tape to male threads before assembly — do not apply sealant to female ports. Hand-tighten first, then use a pipe wrench to bring the fitting to a snug, leak-free fit without over-torquing the brass body.
