Midland Industries 40007 Brass Pipe Nipple 1/8 Mpt 4 in

Product Description

The MIDLAND INDUSTRIES 40007 is a seamless red brass pipe nipple with 1/8 in male pipe thread (MPT) connections on both ends. It measures 4 inches in length and is manufactured from lead-free red brass, making it suitable for potable water, gas, and general fluid service applications. The nipple carries a Schedule 40 wall rating with a pressure class of 125 lb and a working pressure of 370 psi at 100 degrees F. Thread form conforms to 1/8-27 NPT per ANSI B1.20.1. Licensed plumbers and HVAC technicians install this fitting as a close-quarter connector in manifolds, gauges, valves, and instrument ports.

This nipple is designed for use in residential and light commercial plumbing, HVAC, and gas distribution systems where a short, rigid male-to-male connection is required. Its compact 4 in length suits tight installations behind walls, inside equipment cabinets, or on boiler trim assemblies. The lead-free red brass construction meets requirements for use in potable water systems. It handles a broad service temperature range of -20 to 400 degrees F, covering both chilled water and low-pressure steam applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC requirements. Shut off supply pressure and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a properly sized pipe wrench and back-up wrench to avoid stressing downstream connections.
