Merit Brass C101-04 Brass Pipe Fitting 1/4 in Fnpt Class 125

Product Description

The MERIT BRASS C101-04 is a 1/4 inch Class 125 brass pipe fitting with female NPT connections on both ends. It provides a threaded union point between two sections of pipe or between a pipe and a threaded port on equipment. Class 125 ratings make this fitting appropriate for low-to-moderate pressure service in water, air, and compatible fluid systems. Plumbers, HVAC technicians, and pipefitters install this type of fitting during new construction, system repairs, and equipment connections where a compact, reliable threaded joint is required.

This fitting is suited for residential and light commercial plumbing and mechanical systems. Typical applications include connecting threaded pipe runs, adapting to threaded valve ports, and joining pipe to equipment inlets or outlets. The FNPT x FNPT configuration accepts standard male NPT pipe threads on both sides, making it compatible with common iron, brass, and copper-threaded piping components found throughout plumbing and HVAC systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician following applicable IPC or local plumbing code requirements. Shut off system pressure and drain the line before removing or installing threaded fittings. Apply thread sealant tape or compound to the male threads being engaged, not the female threads on this fitting. Do not overtighten, as brass threads can be damaged by excessive torque.
