Midland Industries 57277 Pipe Nipple 1-1/4 in Mpt 72 in Sch 40

Product Description

The MIDLAND INDUSTRIES 57277 is a welded black steel pipe nipple rated for Schedule 40 service. It measures 72 inches in length with a 1-1/4 inch diameter and male pipe thread (MPT) connections on both ends. Wall thickness is 0.14 inches, and thread engagement length is 1.01 inches per end. Rated to 1,300 psi and suitable for temperatures from -150 degrees F to 200 degrees F, this nipple is a standard component in gas, oil, and industrial piping systems. Licensed plumbers and pipefitters install it where a long-run threaded connection is required between fittings, valves, or equipment.

This nipple is used in residential and commercial black iron gas piping, as well as hydronic heating and general industrial pipe runs where a Schedule 40 steel fitting is specified. The 72-inch length makes it well suited for spanning longer distances between threaded connections without additional couplings. It conforms to ANSI B1.20.1 dimensional standards, making it compatible with standard NPT fittings and valves across the trade.

Compatibility

Designed as a standard OEM-style replacement or new-installation component for Schedule 40 black steel threaded piping systems using 1-1/4 inch NPT fittings and valves.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the piping system completely before threading or removing any fittings. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before making up the joint. Do not over-tighten threaded connections, as this can damage threads or crack fittings.
