Merit Brass XB116-08 Brass End Cap 1/2 in Threaded Fbspt

Product Description

The MERIT BRASS XB116-08 is a 1/2 inch threaded brass pipe end cap rated at Class 125. It seals the terminal end of a threaded pipe run, blocking flow and pressure at the termination point. The end connection is female British Standard Pipe Taper (FBSPT), allowing it to thread directly onto male-threaded pipe ends. At 0.132 pounds, it is a compact fitting suited for use in low-to-moderate pressure plumbing and piping assemblies. Plumbers and pipefitters install this fitting to close off unused branch lines, cap test ports, or terminate temporary or permanent pipe ends in a clean, pressure-rated manner.

This end cap is used in residential and light commercial plumbing, gas distribution, compressed air, and general fluid-handling systems where a 1/2 inch FBSPT threaded termination is required. It is appropriate for applications demanding a Class 125 pressure-rated brass fitting. The all-brass construction resists corrosion and holds up in wet or humid environments typical of mechanical rooms, utility spaces, and exposed pipe runs.

Key Features

• 1/2 inch FBSPT threaded end connection for direct installation onto male-threaded pipe
• Class 125 pressure rating suitable for standard plumbing and piping service
• Brass construction provides corrosion resistance in wet and humid environments
• Compact and lightweight at 0.132 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch male-threaded pipe ends requiring a Class 125 FBSPT brass end cap in plumbing, compressed air, and fluid-handling piping systems.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the pipe system completely before threading on the cap. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before installation to ensure a leak-free seal. Tighten to hand-tight plus wrench-snug; avoid over-tightening, which can crack brass fittings.
