Merit Brass 3004-400 Brass Pipe Nipple 4 in 1/4 Npt Chrome

Product Description

The MERIT BRASS 3004-400 is a chrome-plated red brass pipe nipple threaded on both ends, designed for use in plumbing supply and distribution systems. Measuring 4 inches overall length with 1/4 inch NPT threads, this nipple provides a secure, leak-resistant connection between fittings, valves, and fixtures. The chrome finish over red brass construction resists corrosion and offers a clean appearance in exposed installations. Red brass delivers better corrosion resistance than standard yellow brass, making it a reliable choice for water service applications. Licensed plumbers and pipefitters install this nipple as a direct replacement or new-installation component in residential and light commercial systems.

This nipple is suited for residential and light commercial plumbing applications where a short, fully threaded connector is needed between two female-threaded components. Common uses include connecting shut-off valves, angle stops, supply lines, and fixture fittings. The chrome plating makes it appropriate for above-trim or exposed installations such as under-sink supply connections and lavatory rough-ins where appearance matters alongside function. It is compatible with standard 1/4 inch NPT female-threaded fittings and valves.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the supply line before removing or installing any threaded nipple. Apply thread sealant tape or pipe compound to the male threads before hand-tightening, then wrench-tighten to a snug fit — avoid over-torquing, which can crack fittings. Inspect for leaks after restoring pressure.
