Merit Brass 2104-1800 Brass Pipe Nipple 1/4 Npt 18 in

Product Description

The MERIT BRASS 2104-1800 is a red brass pipe nipple threaded on both ends, designed for use in low-pressure piping systems across plumbing, HVAC, and light industrial applications. It measures 18 inches in overall length with a 1/4 inch NPT thread standard and a 1/4 inch outside diameter. The red brass construction provides solid corrosion resistance in water, steam, and gas service lines. This nipple is OSHA-compliant and weighs 0.66 pounds. Licensed plumbers and pipefitters commonly use nipples of this type to extend or connect threaded pipe runs in tight or custom-length situations where standard close nipples or hex nipples are not practical.

This nipple suits residential and commercial piping installations where 1/4 inch NPT fittings are required. Common applications include supply lines, fuel gas piping, compressed air distribution, and hydronic heating systems. The 18 inch length makes it a good fit for situations requiring a longer threaded pipe extension between fittings, valves, or manifolds. It can be installed horizontally or vertically depending on the system layout and is compatible with standard 1/4 inch NPT threaded fittings and valves.

Compatibility

Designed as an OEM-style replacement or new-install component for threaded piping systems using 1/4 inch NPT connections in plumbing, HVAC, and light industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off and depressurize the system completely before removing or installing threaded nipples. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a leak-free connection. Do not over-torque the fitting, as this can crack the brass or distort the threads.
