The MERIT BRASS 2124-600 is a brass pipe nipple used to connect or extend threaded pipe runs in plumbing, HVAC, and mechanical piping systems. Measuring 1.5 inches in diameter and 6 inches in length, this nipple threads directly into standard fittings, valves, and equipment connections. Brass construction provides corrosion resistance and reliable performance in both hot and cold water applications. Licensed plumbers and pipefitters install this type of fitting during rough-in and finish work on water supply, compressed air, and low-pressure gas systems.
This nipple is suited for residential and light commercial piping installations where a 1.5-inch threaded connection is required. Common applications include water distribution lines, boiler trim connections, and mechanical room piping. The 6-inch length makes it useful where a short close nipple or hex nipple would be too short but a longer pipe section is unnecessary. Plumbers and pipefitters select this size when making up manifold assemblies or connecting valves and union fittings in tight spaces.
Designed as an OEM-style replacement or new-installation fitting for standard 1.5-inch NPT threaded plumbing and mechanical piping systems.
Installation should be performed by a licensed plumber or qualified pipefitter following applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water or gas supply before removing or installing any threaded fitting. Apply thread sealant tape or pipe joint compound to male threads before assembly, and tighten with a pipe wrench to achieve a leak-free connection. Do not overtighten brass fittings, as the material can crack if excessive force is applied.
