B K/mueller 565-055HC Galvanized Pipe Nipple 1x5.5 in

Product Description

The B K/Mueller Industries 565-055HC is a galvanized steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and general mechanical systems. Measuring 1 inch in diameter and 5.5 inches in length, this close-cut nipple serves as a reliable connector between fittings, valves, and other threaded components. The galvanized coating provides corrosion resistance suited to water supply, gas distribution, and industrial piping applications. Licensed plumbers and pipefitters install this type of nipple as part of both new construction and retrofit work where threaded iron pipe systems are specified.

This nipple is appropriate for residential and light commercial plumbing and mechanical systems that use standard NPT threaded iron pipe. Typical applications include water supply lines, hydronic heating distribution, compressed air systems, and gas piping where local codes permit threaded galvanized fittings. The 1-inch diameter suits mains and branch lines in moderate-flow applications. Sold in a package quantity of 10 units, making it a practical choice for contractors completing multiple connections on a single job.

Key Features

• Galvanized steel construction provides corrosion resistance for wet and outdoor-adjacent environments
• 1-inch nominal diameter with standard NPT threading for compatibility with standard iron pipe fittings
• 5.5-inch length suits close offset connections between fittings, valves, and manifolds
• Packaged in quantities of 10 for job-site efficiency
• Suitable for plumbing, gas, hydronic, and compressed air systems where threaded galvanized pipe is specified

Compatibility

Designed as a standard NPT-threaded galvanized pipe nipple for use with 1-inch iron pipe fittings, valves, and couplings in threaded pipe systems.

Installation Notes

Installation of threaded pipe nipples should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code (IPC) or applicable local codes. Always shut off the water supply or isolate the gas or air line before making or breaking threaded connections. Use pipe thread sealant tape or compound rated for the intended service — confirm suitability for gas service separately before applying to gas lines. Do not over-tighten threaded connections; thread engagement should follow standard NPT practice to avoid stress cracking of fittings.
