Merit Brass 3016-400 Brass Pipe Nipple 4 in 1 in Npt Chrome

Product Description

The MERIT BRASS 3016-400 is a chrome-plated red brass pipe nipple designed for threaded piping assemblies in plumbing, HVAC, and mechanical systems. It measures 4 inches overall length (OAL) with 1-inch NPT threads on both ends, providing a full-thread connection suitable for joining pipe fittings, valves, and other threaded components. The chrome finish over red brass offers corrosion resistance and a clean appearance, making it appropriate for exposed installations such as supply lines, fixture connections, and visible piping runs. Licensed plumbers and mechanical contractors are the typical installers for this type of fitting.

This pipe nipple is suited for residential and light commercial plumbing applications where a short, close-coupled threaded connection is required. Common install scenarios include water supply lines, boiler piping, fixture risers, and hydronic heating systems. The 1-inch NPT size fits standard iron pipe size fittings and valves in that nominal pipe diameter. The chrome-plated exterior makes it a practical choice where the fitting will remain visible after installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not overtighten, as red brass fittings can crack under excessive torque.
