Merit Brass XNL106-06 Straight Pipe Tee 3/8 in Fnpt 125 Lb Brass

Product Description

The MERIT BRASS XNL106-06 is a straight pipe tee designed for threaded piping systems in plumbing, HVAC, and general fluid-handling applications. Machined from brass with a rough finish, this fitting connects three sections of pipe at a 90-degree branch in a standard tee configuration. It accepts 3/8 inch nominal female national pipe taper (FNPT) connections on all three ports and carries a 125 lb pressure rating. Licensed plumbers and pipefitters install this type of fitting during new construction, retrofit, and repair work on water, air, and compatible fluid lines.

This tee fits standard 3/8 inch nominal threaded pipe runs found in residential and light commercial systems. Typical applications include potable water distribution, compressed air supply lines, hydronic heating circuits, and general-purpose plumbing branch connections. The FNPT end style requires male NPT pipe threads or fittings on all mating connections. It is suited for installations where a durable, corrosion-resistant brass fitting is preferred over iron or plastic alternatives.

Key Features

• 3/8 inch nominal size fits standard threaded pipe systems
• FNPT connections on all three ports for straightforward threaded assembly
• 125 lb pressure-rated construction for general-service piping
• Brass material provides corrosion resistance in water and air service
• Rough finish allows for reliable thread engagement with pipe dope or PTFE tape
• Straight tee geometry for equal-branch flow distribution

Compatibility

Designed as an OEM-style threaded replacement fitting compatible with 3/8 inch nominal NPT piping systems in residential and commercial plumbing and HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off the water or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply PTFE tape or an approved pipe thread sealant compound to the male threads before assembly to ensure a leak-free joint. Do not over-tighten brass fittings, as excessive torque can crack the fitting body.
