B K Mueller 566-030HN Galvanized Pipe Nipple 1-1/4x3

Product Description

The B K Mueller Industries 566-030HN is a galvanized steel pipe nipple used to connect threaded pipe sections in water supply, gas distribution, and general plumbing systems. Measuring 1-1/4 inches in diameter and 3 inches in length, this close-cut nipple provides a short, rigid threaded connection between fittings, valves, or pipe runs. The hot-dip galvanized coating provides corrosion resistance suitable for both above-ground and damp-environment installations. Plumbers and pipefitters install these nipples in commercial and residential systems wherever a short male-threaded extension is needed. Sold in packages of 5.

This nipple is used in residential and light commercial plumbing, fire sprinkler supply lines, industrial piping, and mechanical room installations. The 1-1/4-inch nominal size is common in branch and main supply runs, boiler connections, and gas piping manifolds. The galvanized finish makes it appropriate for potable water and general-service threaded pipe assemblies where bare steel would be prone to rust.

Key Features

• 1-1/4-inch nominal diameter with NPT male threads on both ends
• 3-inch overall length for tight-clearance threaded connections
• Galvanized steel construction for corrosion resistance in wet or damp environments
• Sold in a package of 5 units for job-lot efficiency
• Compatible with standard NPT threaded fittings and valves

Compatibility

Designed as an OEM-style replacement or standard-stock nipple compatible with 1-1/4-inch NPT threaded pipe fittings, couplings, elbows, and valves used in residential and commercial plumbing and gas piping systems.

Installation Notes

Licensed plumbers and pipefitters typically install galvanized nipples following IPC or IFGC guidelines depending on the service application. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Shut off water supply or gas service and relieve system pressure before removing or installing any threaded pipe component. Do not overtighten threaded connections, as this can crack fittings or distort threads.
