Merit Brass 2102-350 Brass Pipe Nipple 1/8 Npt 3.5 in

Product Description

The MERIT BRASS 2102-350 is a red brass pipe nipple threaded on both ends, designed for joining pipe sections or connecting fittings in low-pressure plumbing, gas, and instrumentation lines. It measures 3.5 inches overall length with a 1/8 inch NPT thread standard and a 1/8 inch outside diameter. Manufactured from red brass, this nipple offers reliable corrosion resistance in water and steam service. It meets OSHA standards and is suited for use by licensed plumbers, HVAC technicians, and pipefitters working on small-diameter connections in both residential and light commercial systems.

This nipple is a standard close-tolerance fitting for 1/8 inch NPT threaded systems. Typical applications include instrumentation taps, pressure gauge connections, pilot lines, and small-bore plumbing tie-ins. The 3.5 inch OAL gives enough thread engagement on both ends for secure assembly in tight spaces or where an extension between two threaded ports is required. Plumbers and mechanical contractors commonly stock this size for service work on boilers, compressed air lines, and water distribution systems.

Key Features

• Threaded on both ends for direct connection between two female-threaded fittings or ports
• 1/8 inch NPT thread standard for compatibility with standard tapered pipe threads
• 3.5 inch overall length provides clearance for close-quarter installations
• Red brass construction resists corrosion in water, steam, and mild gas service
• Meets OSHA standards for workplace plumbing and piping applications

Compatibility

Designed as a standard OEM-style replacement or new-installation fitting for any system using 1/8 inch NPT threaded connections, including plumbing, HVAC, boiler, and instrumentation piping assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the system type. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly. Shut off and depressurize the line completely before removing or installing any threaded pipe fitting. Do not over-tighten brass fittings, as the material is softer than steel and susceptible to thread damage under excessive torque.
