B K Mueller 561-035HC Galvanized Pipe Nipple 1/4 X 3.5 in

Product Description

The B K Mueller Industries 561-035HC is a galvanized steel pipe nipple used for joining threaded pipe sections in plumbing, gas, and mechanical piping systems. Measuring 0.25 inches in diameter and 3.5 inches in length, this short nipple provides a rigid, corrosion-resistant connection suitable for a wide range of trade applications. The hot-dip galvanized finish protects against rust and corrosion in both exposed and concealed installations. Licensed plumbers and pipefitters are the primary installers. Each package contains 10 nipples, making it practical for job-lot procurement on larger projects.

This galvanized nipple is suited for residential and light commercial plumbing, gas supply piping, and general mechanical systems where threaded steel pipe is specified. The 0.25-inch diameter is commonly found in branch lines, drip legs on gas systems, and low-pressure utility connections. The 3.5-inch length bridges short offsets and provides adequate thread engagement on both ends.

Key Features

• Galvanized steel construction for corrosion resistance in damp or exposed environments
• 0.25-inch nominal pipe size with 3.5-inch overall length
• Threaded on both ends for standard NPT connections
• Sold in a package of 10 for project-quantity purchasing
• Compatible with standard threaded pipe fittings and valves

Compatibility

Designed as a standard NPT-threaded galvanized pipe nipple suitable for use with 0.25-inch threaded pipe fittings, valves, and couplings in plumbing and mechanical piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters using pipe wrenches and appropriate thread sealant or PTFE tape rated for the intended service. Shut off supply pressure and depressurize the line before removing or installing any threaded fittings. Follow applicable local plumbing codes, the International Plumbing Code (IPC), and International Fuel Gas Code (IFGC) requirements for pipe joint compound and thread engagement minimums. Do not over-tighten threaded connections, as this can crack fittings or strip threads.
