Nipples 331025007 Galvanized Steel Pipe Nipple 1 in Mnpt Sch 40

Product Description

The NIPPLES 331025007 is a Schedule 40 galvanized steel pipe nipple designed for use in piping systems carrying air, gases, non-potable water, and oils. It features a 1-inch MNPT (male national pipe thread) connection on one end and a 5-inch threaded-both-ends (TBE) configuration. The galvanized finish provides corrosion resistance suitable for industrial and mechanical applications. Constructed from Grade B steel using a welded pipe process, this nipple is rated for a maximum operating pressure of 150 psi at 150 degrees F. It is manufactured in the United States.

This pipe nipple is suited for residential and commercial mechanical systems where a short threaded male fitting is needed to connect valves, couplings, or other threaded pipe fittings. Common applications include HVAC piping, compressed air lines, gas distribution systems, and general industrial fluid handling. The 1-inch nominal pipe size makes it a standard fitting in many existing piping assemblies.

Compatibility

Designed as a standard Schedule 40 threaded pipe nipple compatible with 1-inch MNPT fittings, valves, and couplings in air, gas, oil, and non-potable water piping systems.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters following applicable local mechanical and plumbing codes, including IPC and IFGC requirements where relevant. Shut off all system pressure and depressurize the line before removing or installing threaded nipples. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or strip threads.
