Midland Industries 57110 Pipe Nipple 1 in Mpt 7 in Sch 40 Steel

Product Description

The MIDLAND INDUSTRIES 57110 is a Schedule 40 welded pipe nipple designed for threaded pipe assemblies in gas, water, and industrial fluid systems. It features 1-inch male pipe thread (MPT) connections on both ends and measures 7 inches in overall length with a 1-inch diameter. Wall thickness is 0.133 inches, consistent with SCH 40 steel specifications. Constructed from black steel, this nipple is rated for pressures up to 700 psi and a temperature range of -150 to 200 degrees F. Thread length is 0.98 inches per end, conforming to ANSI B1.20.1 dimensional standards. Plumbers, pipefitters, and mechanical contractors install this fitting in both residential and light commercial applications.

This nipple is suited for black steel gas piping, hydronic heating systems, compressed air lines, and general-purpose threaded pipe runs. The SCH 40 wall rating makes it appropriate for moderate-pressure service. It is commonly used to connect valves, unions, tees, and other threaded fittings where a rigid close-to-medium-length nipple is needed. Its black finish is standard for natural gas and propane distribution piping in interior applications.

Key Features

• 1-inch MPT on both ends for direct connection to standard NPT fittings and valves
• Schedule 40 wall thickness (0.133 inches) for moderate-pressure service up to 700 psi
• 7-inch overall length provides clearance for offset connections in tight runs
• Thread dimensions conform to ANSI B1.20.1 for consistent fitment
• Black steel construction rated from -150 to 200 degrees F
• Welded construction with 0.98-inch thread engagement length per end

Compatibility

Designed as an OEM-style replacement or new-installation component compatible with standard 1-inch NPT threaded fittings, valves, and pipe connections in SCH 40 black steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or IPC requirements for water and mechanical systems. Apply thread sealant or PTFE tape rated for the intended service medium before assembly. Do not over-tighten threaded connections; use a pipe wrench on the fitting body, not on pipe threads. Shut off and depressurize the line and verify zero pressure before cutting into any existing system.
