Midland Industries 57247 Pipe Nipple 1/2 in Mpt 72 in Sch 40

Product Description

The MIDLAND INDUSTRIES 57247 is a welded black steel pipe nipple designed for threaded piping systems requiring a full-length close-coupled connection. Sized at 1/2 inch diameter with male pipe threads (MPT) on both ends, this nipple measures 72 inches in length and carries a Schedule 40 wall thickness of 0.109 inches. It is rated for up to 700 psi working pressure and a temperature range of -150 to 200 degrees F, making it well suited for gas, air, and general-purpose fluid distribution lines. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers of this component.

This nipple is used in residential and light commercial piping applications where a long-run threaded steel connection is needed without field cutting and threading. Common install scenarios include natural gas branch lines, compressed air distribution, steam systems, and fire suppression lateral runs. The black finish indicates no galvanizing, which is the correct choice for gas piping per applicable codes. The 72-inch length allows a single-piece run between fittings where longer spans are required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the supply line fully before threading this nipple into the system. Apply an approved thread sealant or PTFE tape rated for the intended service medium before making up the joints. Do not over-tighten connections; check all joints for leaks after restoring system pressure.
