Midland Industries 56149 Galvanized Pipe Nipple 1-1/2 in Sch 40

Product Description

The MIDLAND INDUSTRIES 56149 is a Schedule 40 galvanized steel welded pipe nipple with 1-1/2 inch male pipe thread (MPT) connections on both ends and an overall length of 6 inches. It is rated to 1,300 psi and handles temperatures from -150 to 200 degrees F, making it a dependable short-run connector for water, gas, and general piping systems. The hot-dip galvanized finish provides corrosion resistance suited to exposed or mildly corrosive environments. Thread dimensions conform to ANSI B1.20.1. Plumbers and pipefitters install this fitting during new construction and retrofit work where a rigid, full-bore connection between threaded components is required.

This nipple is used in residential and light commercial plumbing, HVAC hydronic piping, gas distribution, and industrial process piping where NPT threaded steel pipe is the specified material. The 6-inch body length suits close-quarter runs where a longer pipe section is impractical but a close nipple would be too short. The SCH 40 wall thickness supports standard working pressures found in most building mechanical systems.

Key Features

• Schedule 40 wall thickness of 0.145 inches for full-rated working pressure
• 1,300 psi pressure rating for demanding piping applications
• ANSI B1.20.1 thread standard ensures compatibility with standard NPT fittings and valves
• Galvanized steel construction resists corrosion in wet and outdoor environments
• Temperature range of -150 to 200 degrees F covers most mechanical system operating conditions
• 1.03-inch thread engagement length on each end provides secure, leak-resistant makeup

Compatibility

Designed as a standard replacement or new-installation nipple for Schedule 40 galvanized steel NPT threaded piping systems conforming to ANSI B1.20.1 dimensional standards.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before makeup; do not apply sealant to the first two threads. Tighten to hand-tight plus the appropriate number of turns per the fitting manufacturer and applicable code requirements under IPC or IFGC as applicable to the service.
