Midland Industries 40050 Brass Pipe Nipple 3/8 Mpt 6 in

Product Description

The MIDLAND INDUSTRIES 40050 is a seamless red brass pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, gas distribution, and industrial fluid-handling applications. Constructed from lead-free red brass, it measures 6 inches in length with 3/8-inch male pipe thread (MPT) on both ends. The nipple carries a Schedule 40 rating and a 125 lb pressure class, with a maximum working pressure of 890 psi at 100 degrees F. The 0.09-inch wall thickness and seamless construction give it consistent strength across the full length. Licensed plumbers, pipefitters, and HVAC technicians use this fitting to extend or connect threaded pipe runs.

This nipple is suited for residential and light commercial plumbing and mechanical systems where a short threaded extension is needed between valves, fittings, or equipment ports. The 3/8-inch diameter makes it a common choice for domestic water supply lines, low-pressure gas piping, hydronic heating circuits, and compressed air distribution. Its wide service temperature range of -20 to 400 degrees F makes it adaptable to hot and cold fluid service without material degradation.

• 0.09-inch wall thickness with 0.495-inch ID and 0.675-inch OD

Compatibility

Designed as a standard OEM-style replacement or new-installation fitting for 3/8-inch NPT threaded pipe systems, compatible with any valve, fitting, or equipment port conforming to ANSI B1.20.1 thread standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the affected line before disassembly or installation. Apply an approved thread sealant or PTFE tape to the male threads before assembly; do not overtighten, as brass threads can gall or crack under excessive torque. Confirm that the working pressure and temperature of the system do not exceed the rated limits of this fitting.
