Merit Brass C116-04 Brass End Cap 1/4 Inch Fnpt Class 125

Product Description

The MERIT BRASS C116-04 is a brass pipe end cap rated Class 125 with a 1/4 inch female NPT (FNPT) connection. End caps are used to close off the terminal end of a threaded pipe run, preventing flow or pressure loss at open pipe terminations. This fitting is constructed of brass, making it well suited for plumbing, HVAC hydronic lines, compressed air, and general fluid-handling applications where a durable, corrosion-resistant closure is required. At 0.05 pounds, it is a compact, lightweight fitting installed by plumbers, pipefitters, and HVAC technicians during system construction or maintenance.

This end cap is appropriate for residential and light commercial piping systems where Class 125 pressure ratings are sufficient. It threads directly onto a 1/4 inch male NPT pipe end and is commonly used to cap off branch lines, test ports, or decommissioned pipe runs. Its brass construction is compatible with water, air, and many non-corrosive fluid systems in both new construction and retrofit applications.

Key Features

• 1/4 inch FNPT connection threads onto standard 1/4 inch male NPT pipe ends
• Class 125 pressure rating suitable for general-purpose plumbing and HVAC piping
• Brass construction provides corrosion resistance and long service life
• Compact and lightweight at 0.05 pounds for easy handling and installation
• Closes off open pipe terminations to maintain system integrity

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1/4 inch NPT threaded pipe systems rated at Class 125 or below.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off system pressure and depressurize the line before threading the cap onto the pipe end. Apply thread sealant tape or pipe compound to the male threads before assembly to ensure a leak-free seal. Do not overtighten, as brass fittings can crack if subjected to excessive torque.
