Midland Industries 56040 Galvanized Pipe Nipple 3/8 in Mpt 1 in

Product Description

The MIDLAND INDUSTRIES 56040 is a close-pattern galvanized steel pipe nipple rated for Schedule 40 service at 150 lb pressure class. Threaded 3/8-18 NPT male on both ends, it measures 1 inch in overall length with a thread engagement length of 0.6 inches and a wall thickness of 0.091 inches. Working pressure is rated to 700 psi. This fitting is used by plumbers, pipefitters, and HVAC technicians to extend, connect, or adapt threaded pipe runs in low-pressure gas, water, and air distribution systems. The galvanized finish provides corrosion resistance in exposed or mildly corrosive service environments.

The 56040 is suited for residential and light commercial plumbing, gas supply, and compressed air piping applications. Its 3/8 in male pipe thread on both ends makes it a straightforward close nipple for tight-space installations where a longer nipple would be impractical. Installers typically use it when connecting valves, regulators, strainers, or other threaded fittings in SCH 40 pipe assemblies. The galvanized coating makes it appropriate for above-ground installations where moisture exposure is a factor.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Apply thread sealant or PTFE tape rated for the intended service medium before making up the joint. Hand-tighten first, then use a pipe wrench to achieve proper thread engagement without over-torquing. Always depressurize and isolate the line before removing or replacing any threaded fitting.
