Midland Industries 56026 Galvanized Steel Pipe Nipple Sch 40

Product Description

The MIDLAND INDUSTRIES 56026 is a galvanized steel welded pipe nipple rated for Schedule 40 service. It connects two 1/4-inch male pipe thread (MPT) fittings with an overall length of 4 inches and a wall thickness of 0.068 inches. Built from steel with a galvanized finish, this nipple resists corrosion in moderate-moisture environments. It carries a 700 psi pressure rating and a temperature range of -150 to 200 degrees F, making it suitable for low-pressure gas, water, and air distribution lines. Plumbers and pipefitters install this fitting during rough-in and service work wherever a short threaded extension is needed between fittings or valves.

This nipple is used in residential and light commercial plumbing, HVAC, and compressed-air systems. It suits installations requiring a 4-inch threaded extension between two 1/4-inch female-threaded components. The galvanized finish makes it appropriate for exposed or semi-exposed piping runs where bare steel would be susceptible to surface corrosion. The thread form conforms to ANSI B1.20.1, ensuring compatibility with standard NPT fittings found throughout domestic plumbing and mechanical systems.

Key Features

• Schedule 40 wall thickness of 0.068 inches for standard-duty pressure service
• 700 psi maximum pressure rating suitable for water, air, and low-pressure gas lines
• Galvanized steel construction provides corrosion resistance in moisture-prone environments
• 1/4-18 thread form compliant with ANSI B1.20.1 for broad NPT fitting compatibility
• Operating temperature range of -150 to 200 degrees F
• Both ends are 1/4 in MPT for straightforward threaded assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1/4-inch NPT threaded connections in SCH 40 galvanized steel piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC requirements. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to male threads before assembly, and hand-tighten before using a pipe wrench to avoid cross-threading. Do not exceed the rated working pressure of 700 psi.
