B K Mueller 563-120HN Galvanized Pipe Nipple 1/2 X 12 in

Product Description

The B K Mueller Industries 563-120HN is a galvanized steel pipe nipple measuring 0.5 inches in diameter by 12 inches in length. This close-threaded fitting connects two female-threaded pipe fittings or valves in water supply, gas distribution, and mechanical piping systems. The hot-dip galvanized zinc coating provides corrosion resistance in damp or exposed environments. Plumbers and pipefitters install these nipples during new construction, retrofit, or repair work where a short, fixed-length threaded extension is needed between components. Each unit is sold in a package of 15.

This nipple is suited for residential and light commercial plumbing, HVAC hydronic systems, and industrial piping applications where standard NPT-threaded galvanized pipe connections are specified. Common uses include water distribution risers, gas line extensions, and mechanical room piping assemblies. The 12-inch length makes it appropriate for close-clearance installations that require a rigid, pre-cut threaded section rather than cut-to-length pipe.

Key Features

• Galvanized zinc coating for corrosion resistance in wet and exposed environments
• 0.5-inch nominal pipe size with standard NPT threads on both ends
• 12-inch overall length provides a fixed, ready-to-install dimension
• Sold in packages of 15 units for jobsite or shop stocking
• Compatible with standard NPT female fittings, valves, and couplings

Compatibility

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

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape applied to the male threads. Shut off and depressurize the supply line before making or breaking any threaded connection. Follow local plumbing code requirements, including applicable sections of the IPC or IFGC, for approved use of galvanized pipe in potable water or gas service. Do not overtighten threaded connections, as this can crack fittings or distort thread engagement.
