Merit Brass XB116-20 Brass Pipe End Cap 1-1/4 in Fbspt

Product Description

The MERIT BRASS XB116-20 is a Class 125 brass pipe end cap designed to terminate open pipe ends in plumbing, HVAC, and light industrial piping systems. Sized at 1-1/4 inches with a female British Standard Pipe Taper (FBSPT) end connection, this fitting threads directly onto male-threaded pipe to seal off a run cleanly and permanently. The brass construction resists corrosion in both water and air lines. Licensed plumbers and pipefitters install this fitting during system commissioning, pressure testing, and pipe capping applications where a durable metal closure is required.

This end cap suits residential and light commercial piping installations where Class 125 pressure ratings are appropriate. Common applications include capping unused branch outlets, closing off test ports, and terminating supply lines during phased construction. The FBSPT thread pattern is standard across a wide range of pipe systems, making this cap a practical stock item for service vans and shop inventory alike.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the line completely before threading the cap onto the pipe. Apply thread sealant tape or compound to the male threads before installation to ensure a leak-free seal. Do not over-tighten brass fittings, as excessive torque can crack the fitting body.
