Merit Brass C116-06 Brass End Cap 3/8 in Fnpt Class 125

Product Description

The MERIT BRASS C116-06 is a Class 125 brass pipe end cap designed to terminate open pipe ends in threaded piping systems. The fitting accepts a 3/8 inch female NPT connection, allowing it to thread directly onto male pipe ends to seal off a line. Constructed from brass, it is well suited for use in plumbing, gas, air, and light industrial fluid systems where a reliable, pressure-rated mechanical termination is required. Licensed plumbers and pipefitters install this type of fitting during new construction, system modifications, and service work.

This end cap is appropriate for residential and light commercial piping applications where FNPT threaded pipe terminations are standard practice. Typical uses include capping unused branch outlets, sealing pipe stubs during phased construction, and closing off service ports. Its Class 125 rating makes it compatible with low-to-medium pressure service lines commonly found in potable water, compressed air, and gas distribution systems.

Key Features

• 3/8 inch FNPT threaded connection for direct engagement onto male NPT pipe ends
• Class 125 pressure rating suitable for low-to-medium pressure piping service
• Brass construction offers corrosion resistance and durability in wet and gas service environments
• Compact end cap profile for use in tight pipe configurations
• Threaded design requires no special tools or welding for installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch FNPT threaded piping systems rated to Class 125 service.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements depending on the service medium. Depressurize and isolate the piping system completely before threading on the cap. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before engagement. Hand-tighten first, then use a pipe wrench to achieve a proper, leak-free connection without overtightening the brass fitting.
