B K Mueller 563-025HN Galvanized Pipe Nipple 0.5x2.5 in

Product Description

The B K Mueller Industries 563-025HN is a galvanized steel pipe nipple sized at 0.5 inches nominal diameter by 2.5 inches in length. Pipe nipples serve as short threaded connectors used to join two female-threaded fittings or to extend a threaded pipe run. This nipple is galvanized for corrosion resistance, making it suitable for water supply, gas distribution, and general mechanical piping applications. Licensed plumbers, pipefitters, and HVAC technicians install nipples routinely as part of rough-in work, equipment connections, and repair tasks. The 563-025HN ships in a package of 15 units, making it practical for contractors managing multiple connection points on a single job.

This nipple is suited for residential and light commercial plumbing and mechanical systems where a short threaded male-to-male connection is required. Common applications include water supply lines, boiler piping, gas line assemblies, and HVAC equipment hookups. The galvanized finish provides a layer of zinc protection against oxidation in damp or exposed environments. At 0.5 inches nominal pipe size and 2.5 inches in length, this nipple fits standard NPT-threaded fittings and valves used throughout the trade.

Compatibility

Designed as a standard NPT-threaded galvanized pipe nipple for use with 0.5 inch female-threaded fittings in plumbing, mechanical, and HVAC piping systems.

Installation Notes

Galvanized pipe nipples are installed by licensed plumbers and pipefitters working under applicable plumbing codes such as the IPC or local jurisdictional equivalents. Shut off the water supply or isolate the gas line and depressurize the system before making any threaded connections. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before tightening. Hand-tighten first, then use a pipe wrench to complete the connection without over-stressing the threads or adjacent fittings.
