Merit Brass NLBS114-0604 Hex Head Pipe Bushing 3/8x1/4 in

Product Description

The MERIT BRASS NLBS114-0604 is a hex head pipe bushing designed to reduce a 3/8 inch female NPT port down to a 1/4 inch male NPT fitting. Rated at 125 lb, this bushing is machined from rough brass and is manufactured domestically. The hex head profile allows standard wrench engagement during installation, making it straightforward to seat and seal in a wide range of threaded pipe assemblies. Plumbers, HVAC technicians, and pipefitters use this type of bushing when transitioning between pipe sizes in low-to-medium pressure service lines.

This bushing suits residential and light commercial applications where a 3/8 inch threaded port needs to accept a 1/4 inch NPT connection. Common install scenarios include instrumentation taps, gauge ports, compressed air lines, water supply branches, and fuel gas distribution systems where pipe size reduction is required at a fitting or valve body. The 125 lb pressure rating aligns with standard service conditions in potable water, steam, and general-purpose plumbing systems.

Key Features

• 3/8 inch to 1/4 inch nominal size reduction in a single fitting
• Male NPT (MNPT) end style for direct threaded engagement
• 125 lb pressure rating suitable for standard service lines
• Brass construction provides corrosion resistance and thread durability
• Hex head profile allows wrench-tight installation without improvised gripping
• Domestic manufacture

Compatibility

Designed as an OEM-style and general-use replacement bushing for 3/8 inch female NPT ports requiring a 1/4 inch male NPT connection in standard 125 lb brass pipe fitting assemblies.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians working under applicable IPC or IFGC codes. Shut off and depressurize the line before removing or installing any threaded fitting. Apply thread sealant tape or pipe dope rated for the service medium to the male threads before engagement. Do not overtighten brass fittings, as the material can crack under excessive torque.
