B K/mueller Inds 568-055HC Galvanized Pipe Nipple 2x5.5 in

Product Description

The B K/MUELLER INDS(IMPORT) 568-055HC is a galvanized steel pipe nipple used in threaded pipe assemblies across plumbing, HVAC, and general mechanical piping systems. Measuring 2 inches in diameter by 5.5 inches in length, this close-cut nipple connects threaded fittings, valves, and pipe runs where a short, rigid section is needed. The hot-dip galvanized zinc coating resists corrosion in both wet and moderate-temperature service environments. Licensed plumbers and pipefitters install this type of nipple as a standard component in supply and distribution lines. Each package contains 5 nipples.

This nipple is suited for residential and light commercial applications including water supply lines, gas distribution headers, boiler piping, and general threaded iron pipe systems. It fits standard NPT threaded fittings and is a common stock item in mechanical rooms, utility piping, and equipment connections where a short rigid offset or extension is needed between components.

Key Features

• Galvanized steel construction provides corrosion resistance for wet and mechanical service environments
• 2-inch nominal diameter fits standard NPT threaded fittings and valves
• 5.5-inch length provides a short rigid extension or offset between threaded components
• Package quantity of 5 nipples per unit reduces procurement trips on multi-connection jobs
• Hot-dip galvanized finish suitable for exposed or semi-exposed piping installations

Compatibility

Designed as an OEM-style replacement or standard stock nipple for use with 2-inch NPT threaded iron pipe fittings in residential and commercial mechanical piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or local mechanical code requirements. Shut off and depressurize the pipe system fully before removing or installing threaded nipples. Apply pipe thread sealant tape or compound rated for the intended service medium to all male threads before making up connections. Do not over-tighten threaded connections, as this can crack cast fittings or distort threads.
