Merit Brass C116-08 Brass End Cap 1/2 Inch Fnpt Class 125

Product Description

The MERIT BRASS C116-08 is a brass pipe end cap rated for Class 125 service. It accepts a 1/2 inch female NPT (FNPT) threaded connection and is used to terminate an open pipe end in a plumbing, HVAC, or light industrial piping system. The FNPT thread pattern provides a secure, pressure-rated seal when combined with appropriate thread sealant or PTFE tape. At 0.15 pounds, this is a compact, single-piece fitting suited for permanent pipe termination work in both new construction and retrofit applications. Plumbers, pipefitters, and HVAC technicians commonly install this type of cap when decommissioning a branch line or capping an unused port.

The C116-08 is appropriate for use in residential and light commercial piping systems where a 1/2 inch threaded end termination is required. Typical applications include capping unused supply lines, branch tees, and service ports in water, air, and compatible fluid distribution systems. The Class 125 pressure rating aligns with standard low-to-medium pressure plumbing service. The brass construction offers corrosion resistance suitable for potable water and hydronic heating systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the supply line before threading on the cap. Apply PTFE tape or approved pipe thread sealant to the male threads before engagement to ensure a leak-free seal. Follow applicable IPC and local plumbing code requirements for thread engagement depth and pressure testing after installation.
