Merit Brass XB112-0804 Brass Reducing Coupling 1/2x1/4

Product Description

The MERIT BRASS XB112-0804 is a brass pipe reducing coupling designed to connect two female threaded pipe ends of different sizes within a plumbing or fluid-handling system. Manufactured to Class 125 standards, this fitting transitions a 1/2-inch line down to a 1/4-inch line using Female British Standard Pipe Taper (FBSPT) threads on both ends. The threaded connection type allows for tool-assisted hand assembly without soldering or crimping equipment. Weighing 0.17 pounds, it is a compact, lightweight component suited for residential and light commercial plumbing, HVAC condensate lines, pneumatic systems, and similar low-to-medium pressure applications. Licensed plumbers and HVAC technicians are the typical installers.

This reducing coupling is appropriate for use in pipe systems where a size reduction is needed between two internally threaded ports or fittings. Common applications include connecting instrument lines, gauge ports, and small-diameter branch lines off a larger supply in plumbing, HVAC, and light industrial settings. The FBSPT x FBSPT configuration makes it suitable for use where both mating fittings carry female pipe threads, requiring an externally threaded nipple or fitting on each connecting component. The Class 125 pressure rating aligns with standard low-pressure water, air, and hydronic system requirements.

Key Features

• Reduces 1/2-inch pipe to 1/4-inch pipe in a single inline fitting
• FBSPT x FBSPT end connections accept externally threaded male fittings on both sides
• Class 125 pressure rating suitable for low-to-medium pressure water, air, and hydronic systems
• Brass construction offers corrosion resistance in wet and humid environments
• Threaded connection eliminates need for soldering or specialty tools
• Compact and lightweight at 0.17 pounds for easy inline installation

Compatibility

Designed as an OEM-style replacement or new-installation reducing coupling for threaded brass pipe systems requiring a 1/2-inch to 1/4-inch FBSPT x FBSPT transition at Class 125 pressure rating.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians in accordance with applicable IPC or IFGC guidelines. Shut off system pressure and drain the line before disassembling or installing any threaded fitting. Apply thread sealant tape or pipe compound to the male threads of the mating fittings before assembly and tighten to snug using appropriate pipe wrenches. Do not overtighten brass fittings, as the material is softer than iron and can crack or strip under excessive torque.
