Merit Brass XNL111-06 3/8 Inch Fnpt Straight Pipe Coupling

Product Description

The MERIT BRASS XNL111-06 is a straight pipe coupling designed to join two sections of pipe in a continuous run. It features female NPT (FNPT) threads on both ends and is rated to 125 lb, making it suitable for moderate-pressure water, gas, and general plumbing applications. Constructed from brass with a rough finish, this coupling is a standard import fitting intended for use by licensed plumbers and pipefitters in residential and light commercial installations.

This coupling is sized at 3/8 inch nominal and fits standard NPT-threaded pipe of the same diameter. It is commonly installed in supply lines, distribution manifolds, and branch connections where a reliable inline threaded joint is needed. The FNPT configuration on both ends allows it to mate with male-threaded pipe or fittings, making it a versatile component in typical pipe assemblies across plumbing and light industrial systems.

Key Features

• Straight coupling design for inline pipe connections with no change in direction
• FNPT threads on both ends for standard NPT compatibility
• 125 lb pressure rating suitable for moderate-pressure service
• Brass construction offers corrosion resistance in water and gas service
• Rough finish for use where appearance is not a factor
• 3/8 inch nominal size for common small-diameter pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch nominal NPT-threaded pipe systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local codes and the International Plumbing Code (IPC). Shut off and depressurize the system before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten brass fittings, as the material can crack under excessive torque.
