Merit Brass XNL114-1204 Hex Head Pipe Bushing 3/4x1/4 Brass

Product Description

The MERIT BRASS XNL114-1204 is a hex head pipe bushing used to reduce a 3/4-inch male NPT connection down to a 1/4-inch female NPT port. Rated at 125 lb, this bushing is machined from brass with a rough finish and is commonly installed in plumbing, HVAC, and compressed air systems where pipe size reductions are required at threaded fittings. The hex head design allows for wrench engagement, making tightening and removal straightforward in tight installations. Plumbers, pipefitters, and HVAC technicians use this type of bushing when adapting between different pipe diameters at valves, gauges, or equipment ports.

This bushing suits residential and light commercial applications where a 3/4-inch threaded line must be reduced to accept a 1/4-inch threaded component. Typical use cases include pressure gauge ports, drain taps, sample ports, and equipment connections in water supply, hydronic heating, refrigeration piping, and general-purpose compressed air distribution. The MNPT x FNPT configuration allows it to thread directly into an existing female fitting while accepting a smaller male-threaded component on the outlet side.

Key Features

• 3/4-inch MNPT inlet to 1/4-inch FNPT outlet reduces pipe size at threaded connections
• Hex head design provides wrench flats for secure installation and removal
• 125 lb pressure rating suitable for low-pressure plumbing and HVAC service
• Brass construction offers corrosion resistance in water, air, and light hydrocarbon service
• Rough finish — suitable for direct installation without cosmetic requirements

Compatibility

Designed as a standard NPT-threaded pipe bushing for use in any 3/4-inch female NPT port requiring a 1/4-inch male NPT reduction across plumbing, HVAC, and compressed air applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off system pressure and drain the line before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with local plumbing codes before assembly. Do not over-torque brass fittings, as the material is softer than steel and susceptible to thread damage under excessive force.
