Product Description

The MIDLAND INDUSTRIES LF122-12 is a lead-free brass hex nipple designed for threaded pipe connections in plumbing, HVAC, and general piping systems. It features 3/4 in male pipe thread (MPT) on both ends and measures 1-3/4 inches in length. The 1.39-inch hex body allows for standard wrench engagement, making installation and removal straightforward. The lead-free brass construction meets drinking water compliance requirements, making this fitting suitable for potable water lines as well as broader piping applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This hex nipple is rated for use with brass or steel pipe in a wide range of residential and light commercial piping systems. Its 3/4-14 thread pitch conforms to standard NPT specifications, ensuring reliable thread engagement across compatible fittings and valves. It is commonly used in water supply lines, gas distribution, and HVAC fluid circuits where a short male-to-male threaded extension is required between two female-threaded components.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off the water supply or gas service and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Do not overtighten, as brass threads can be damaged by excessive force.
