B K Mueller 561-030HN Galvanized Pipe Nipple 1/4x3 in

Product Description

The B K/MUELLER INDS(IMPORT) 561-030HN is a galvanized steel pipe nipple used to create threaded connections in low-pressure plumbing, gas, and industrial piping systems. Measuring 1/4 inch in diameter and 3 inches in length, this close-tolerance nipple is hot-dip or mill galvanized to resist corrosion in exposed or damp environments. The zinc coating makes it suitable for water supply, air lines, and light industrial fluid transfer applications. Licensed plumbers and pipefitters install these nipples as couplings between fittings, valves, and other threaded components. Sold in packages of 10, it is a practical stocking item for service trucks and supply houses.

This nipple is sized at 1/4 inch NPT and 3 inches in length, fitting standard threaded plumbing and gas piping configurations found in residential and light commercial installations. Typical applications include connecting shutoff valves, unions, tees, and elbows in water supply or compressed-air lines. The galvanized finish extends service life in utility rooms, mechanical spaces, and outdoor-adjacent environments where bare steel would corrode prematurely. This nipple is commonly used wherever a short threaded extension is needed between two fittings.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water or air supply before cutting into any existing line. Apply an approved pipe thread sealant or PTFE tape to the male threads before making up the joint. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
