Midland Industries 42120 Close Nipple 1-1/4 in Mpt Brass Sch 80

Product Description

The MIDLAND INDUSTRIES 42120 is a close nipple designed for threaded pipe connections in high-pressure and heavy-duty plumbing systems. Machined from red brass, this fitting connects two female-threaded ports using male pipe thread (MPT) on both ends with no exposed pipe between the threads, forming the shortest possible threaded connection. The 1-1/4-11-1/2 thread form conforms to ANSI B1.20.1, ensuring reliable seating and leak-resistant joints. Rated Schedule 80 Extra Heavy (SCH 80/XH), it handles elevated pressures common in industrial and commercial plumbing lines. Licensed plumbers and pipefitters install this type of fitting in tight-clearance runs where a standard hex nipple would not fit.

This close nipple is suited for residential and commercial plumbing, gas distribution, and industrial piping applications where 1-1/4 inch threaded connections are required. Its red brass construction makes it a common choice in water supply, steam, and low-pressure gas systems where corrosion resistance and pressure integrity are priorities. It fits anywhere a Schedule 80 rated close nipple is called out in 1-1/4 inch nominal pipe size configurations.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as red brass fittings can crack under excessive torque applied with power tools.
