Midland Industries 120AH-BB-BW Breakaway Adapter Brass

Product Description

The MIDLAND INDUSTRIES 120AH-BB-BW is a heavy breakaway adapter designed for connecting and disconnecting threaded pipe assemblies under pressure without tools. It features a 1/4-inch Female NPTF inlet and a 1/4-inch Male NPTF outlet, both threaded at 1/4-18. Constructed from brass, this adapter handles pressures up to 1200 psi and operates across a temperature range of -65 to 250 degrees F. It is a compact, durable fitting suited for plumbing, pneumatic, hydraulic, and industrial piping applications where quick disconnection is required.

This adapter is commonly used in residential and commercial piping systems, pneumatic lines, and light industrial assemblies. Its breakaway design allows a controlled separation point in a line, which is useful in equipment protection or tethered hose applications. Licensed plumbers and pipefitters are the typical installers, though the fitting is also within reach of experienced maintenance technicians. Compatible pipe materials include brass, bronze, copper, steel, aluminum, and iron pipe.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Depressurize and isolate the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPTF threads and tighten to hand-tight plus the appropriate number of turns for NPTF dry-seal threads. Do not overtighten brass fittings, as this can crack the body or distort the sealing surfaces.
