Bk Mueller 561-100HC Galvanized Pipe Nipple 1/4 in 10 in Sch 40

Product Description

The BK MUELLER 561-100HC is a galvanized steel pipe nipple rated at Schedule 40 wall thickness, measuring 1/4 inch nominal pipe size and 10 inches in length. It is threaded on both ends to NPT standards, allowing direct connection to fittings, valves, or other pipe segments without additional machining. The galvanized finish provides corrosion resistance in wet and exposed environments. This nipple is a standard component in low-pressure gas, water distribution, and general plumbing systems. Licensed plumbers and pipefitters install it during rough-in and service work across residential, commercial, and light industrial applications.

This pipe nipple is suited for use in potable water supply lines, hydronic heating systems, natural gas distribution piping, compressed air lines, and general fluid conveyance systems where Schedule 40 galvanized steel is specified. Its 1/4-inch nominal size makes it a common choice for branch lines, instrument connections, and pilot gas supply runs. It is typically installed where corrosion resistance and moderate pressure capacity are both required.

Key Features

• 1/4 inch nominal pipe size with 10-inch overall length
• Threaded on both ends for direct fitting-to-fitting installation
• Hot-dip galvanized steel construction for corrosion resistance in wet and outdoor environments
• Compatible with standard NPT fittings and valves

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 40 galvanized steel piping systems using 1/4-inch NPT threaded fittings and valves.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IPC and IFGC requirements where gas service is involved. Shut off supply pressure and verify the line is depressurized before removing or installing any nipple. Apply a listed thread sealant or PTFE tape to male threads before makeup, and tighten to hand-tight plus wrench turns as appropriate for the fitting material. Do not over-torque connections on brass or plastic fittings mated to this steel nipple.
