Merit Brass X116-02 Brass Pipe End Cap 1/8 in Fnpt

Product Description

The MERIT BRASS X116-02 is a brass threaded pipe end cap rated for Class 125 service. It features a 1/8 inch female NPT (FNPT) threaded connection and is used to close off the open end of a pipe or fitting in low-to-medium pressure piping systems. Weighing 0.03 pounds, this compact cap is machined from brass and is suited for applications where a durable, corrosion-resistant pipe closure is required. Licensed plumbers and pipefitters install this type of fitting during new construction, system modifications, and pressure testing when a line terminus must be sealed.

This end cap is appropriate for residential and light commercial plumbing, gas distribution, compressed air, and other fluid-handling systems that fall within its Class 125 pressure rating of 125 psi. The 1/8 inch FNPT thread size makes it a common choice for capping small-diameter branch lines, instrumentation ports, and test ports. It is sold individually, with a minimum order quantity of 6 units.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable local plumbing codes and the IPC. Shut off system pressure and drain the line before removing or installing any pipe cap. Apply thread sealant tape or pipe dope to the male threads before threading the cap on by hand, then tighten with a wrench to achieve a leak-free seal without overtightening the fitting. Verify system integrity with a pressure test after installation.
