B K/mueller Inds(import) 563-055HN Galvanized Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 563-055HN is a galvanized steel pipe nipple measuring 1/2 inch nominal diameter by 5-1/2 inches in length. Galvanized nipples serve as short threaded connectors between fittings, valves, and pipe runs in gas, water, and general-purpose plumbing systems. The zinc coating provides corrosion resistance suited to exposed or mildly harsh environments. This unit is sold in a package of 10 and is a standard stock item for plumbers and pipefitters working on residential and light commercial installations. The threaded ends accept standard NPT fittings, making it a drop-in addition to existing black or galvanized piping systems.

Galvanized pipe nipples in this size range are commonly used in residential and commercial plumbing, gas distribution, and mechanical piping. The 1/2 inch by 5-1/2 inch dimension suits branch connections, riser drops, valve installations, and close-quarter tie-ins where a longer spool piece is not practical. Plumbers and mechanical contractors typically keep a supply of these on hand for service calls and new construction roughing work.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters in accordance with applicable local plumbing codes and the International Plumbing Code. Shut off water or gas supply and depressurize the line before removing or installing any nipple. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as this can crack cast fittings or damage threads.
