Merit Brass 2102-550 Brass Pipe Nipple 1/8 Npt

Product Description

The MERIT BRASS 2102-550 is a red brass pipe nipple designed for low-pressure plumbing, instrumentation, and fluid-handling applications. It is threaded on both ends to National Pipe Taper (NPT) standard, making it a direct-connect fitting between two female-threaded ports. The nipple measures 5.5 inches overall length with a 1/8 inch NPT thread size and is manufactured from red brass, which offers solid corrosion resistance in water, air, and mild chemical service. It is OSHA compliant and appropriate for use wherever code or site requirements reference that standard. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.

This nipple is suited for residential and light commercial plumbing systems, compressed air lines, gas service lines, and instrumentation tie-ins where a 1/8 inch NPT close or short nipple is required. Its compact diameter and full NPT threading make it a common solution for gauge ports, valve extensions, and branch connections on small-bore piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to NPT threads before makeup and tighten to a snug, leak-free torque using a pipe wrench. Follow applicable IPC and local plumbing code requirements for the specific service fluid and pressure rating.
