Merit Brass 2102-450 Brass Pipe Nipple 1/8 Npt 4.5 in

Product Description

The MERIT BRASS 2102-450 is a red brass pipe nipple threaded on both ends, designed for low-pressure fluid and gas piping connections in residential and light commercial plumbing systems. It measures 4.5 inches overall length with a 1/8 inch NPT thread standard and a 1/8 inch outside diameter. Fabricated from red brass, this nipple offers solid corrosion resistance in wet service environments. At 0.09 pounds, it is a compact fitting suited for tight piping configurations. Licensed plumbers and pipefitters install this fitting as part of threaded piping assemblies where a short, fully threaded connector is required between valves, gauges, or other threaded components.

This nipple is used in residential and light commercial plumbing, HVAC condensate drain systems, fuel gas distribution, and instrumentation piping where 1/8 inch NPT connections are specified. Its fully threaded body allows direct engagement on both ends without the need for additional couplings, making it a straightforward choice for close-quarter piping runs. The red brass construction makes it compatible with copper and brass system components commonly found in potable water, steam, and compressed air service lines.

Key Features

• Threaded on both ends for direct connection to NPT-threaded fittings, valves, and equipment
• Red brass construction provides corrosion resistance in wet and humid service conditions
• 4.5 inch overall length suits compact or close-quarter piping installations
• 1/8 inch NPT thread standard ensures compatibility with standard North American pipe fittings
• OSHA-compliant product designation
• Lightweight at 0.09 pounds, minimizing load on instrumentation or small-bore piping

Compatibility

Designed as a standard replacement or new-installation nipple for 1/8 inch NPT threaded piping systems using red brass or compatible metal fittings in plumbing, HVAC, and instrumentation applications.

Installation Notes

Installation of threaded brass pipe nipples is typically performed by licensed plumbers or pipefitters in accordance with applicable IPC and IFGC code requirements. Shut off all supply pressure and depressurize the line before removal or installation of any threaded fitting. Apply thread sealant tape or paste rated for the service medium to all male threads before assembly. Do not over-tighten brass fittings, as excessive torque can crack the fitting body or distort the thread.
