Midland Industries 56140 Galvanized Pipe Nipple 1-1/2 in Sch 40

Product Description

The MIDLAND INDUSTRIES 56140 is a Schedule 40 galvanized steel close nipple with male pipe thread (MPT) on both ends, sized at 1-1/2 inches in diameter and 1-3/4 inches in length. It carries a 150 lb pressure class rating with a working pressure of 1300 psi, making it a reliable choice for moderate- to high-pressure piping runs. Wall thickness is 0.145 inches. Threads conform to ANSI B1.20.1 at a 1-1/2-11-1/2 thread specification with 1.03 inches of thread engagement length. Licensed plumbers and pipefitters install this fitting in supply, distribution, and utility piping systems.

This nipple is suited for residential and light commercial plumbing, gas distribution, and industrial piping applications where a short, rigid male-to-male threaded connection is required. The galvanized finish provides corrosion resistance in exposed or humid environments. Typical use cases include connecting threaded valves, unions, couplings, and other fittings in Schedule 40 galvanized steel piping systems. Its compact 1-3/4-inch body length makes it useful where space is limited and a close coupling is needed between two threaded components.

Compatibility

Designed as an OEM-style replacement or standard component for Schedule 40 galvanized steel threaded piping systems using 1-1/2 inch NPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the line completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, following local plumbing code requirements such as the IPC or IFGC where applicable. Do not over-tighten; use a pipe wrench sized for 1-1/2 inch fittings and follow standard trade practice for joint engagement.
