Midland Industries 56131 Pipe Nipple 1-1/4 in Sch 40 Galvanized

Product Description

The MIDLAND INDUSTRIES 56131 is a Schedule 40 galvanized steel welded pipe nipple with 1-1/4 inch male pipe thread (MPT) connections on both ends and an overall length of 8 inches. Built to SCH 40 wall thickness standards, it features a 0.14 inch wall and 1.01 inch thread engagement length, providing a reliable threaded connection in pressurized piping systems. Rated to 1300 psi and conforming to ANSI B1.20.1 dimensional standards, this nipple is designed for plumbing, gas distribution, and industrial piping applications handled by licensed plumbers and pipefitters.

This nipple is suited for residential and light commercial piping systems where galvanized steel is specified for corrosion resistance. Typical installations include water supply lines, gas distribution piping, and mechanical room headers. The galvanized finish provides a layer of zinc protection appropriate for moderate-moisture environments. The 8 inch length makes it useful for close-clearance offsets and riser extensions where standard close or short nipples are too short and a longer rigid section is needed.

Key Features

• Schedule 40 wall thickness rated to 1300 psi working pressure
• 1-1/4 inch MPT x MPT connections on both ends for straightforward inline installation
• Galvanized steel construction resists corrosion in moderate-moisture environments
• Conforms to ANSI B1.20.1 thread dimensional standard
• Operating temperature range of -150 to 200 degrees F
• 1.01 inch thread engagement length per end for secure, leak-resistant makeup

Compatibility

Designed as an OEM-style replacement and standard-fitment nipple for Schedule 40 galvanized steel threaded piping systems using 1-1/4 inch NPT fittings, valves, and couplings.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line before removing or installing any threaded fitting. Apply a listed thread sealant or PTFE tape to the male threads before makeup; consult applicable codes such as the IPC or IFGC for approved sealant types in gas service. Do not over-tighten - excessive torque can crack cast fittings mated to the nipple.
