Nipples 331034207 Galvanized Pipe Nipple 1-1/2 in Mnpt Sch 40

Product Description

The NIPPLES 331034207 is a Schedule 40 galvanized steel pipe nipple configured with a 1-1/2 inch Male National Pipe Thread (MNPT) connection and a 5-1/2 inch threaded-both-ends (TBE) body length. Manufactured from Grade B welded steel with a galvanized finish, this nipple is rated for service up to 150 psi at 150 degrees F. The nominal pipe size is 1-1/2 inches, with an inside diameter of approximately 1-39/64 inches and an outside diameter of 1-29/32 inches. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple in threaded piping assemblies where a short, rigid connection between fittings or equipment ports is required.

This nipple is suited for use in air, gas, non-potable water, and oil distribution systems in both residential and commercial applications. The galvanized coating provides corrosion resistance in environments where bare steel would degrade over time. It is a common component in mechanical room piping, compressed air headers, hydronic systems, and fuel gas distribution lines. The MNPT thread pattern is compatible with standard NPT female fittings and valves used throughout industrial and trade plumbing systems. This nipple is made in the USA from Grade B steel.

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 system before removing or installing any threaded pipe components. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or distort threads.
