B K Mueller 562-055HC Galvanized Nipple 3/8x5.5 in 10pk

Product Description

The B K Mueller Industries 562-055HC is a galvanized steel pipe nipple measuring 3/8 inch in diameter and 5.5 inches in length. Pipe nipples are short sections of threaded pipe used to connect two fittings, valves, or other threaded components in a piping system. The galvanized finish provides corrosion resistance, making this nipple suitable for water supply, gas distribution, and general plumbing applications. Sold in a package of 10, this part is a standard item for plumbers and pipefitters maintaining or building threaded piping systems in residential and light commercial settings.

This galvanized nipple is used in threaded piping systems where a short rigid connection is needed between two female-threaded components. Common applications include water supply lines, air distribution systems, and low-pressure gas piping where corrosion resistance is a priority. The 3/8 inch size is frequently found in branch lines, fixture supplies, and instrument connections. Plumbers, pipefitters, and HVAC technicians commonly use close and short nipples like this when assembling or repairing manifolds, valve assemblies, and header connections in both new construction and retrofit work.

Compatibility

Designed as a standard replacement or new-installation threaded pipe nipple compatible with 3/8 inch NPT female-threaded fittings, valves, and couplings used in residential and light commercial plumbing and HVAC piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the intended service. Shut off and depressurize the supply line before removing or installing any threaded pipe components. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
