Merit Brass C114-0806 Brass Pipe Bushing 1/2x3/8 Mnpt Fnpt

Product Description

The MERIT BRASS C114-0806 is a Class 125 brass pipe bushing designed to reduce a 1/2 inch male NPT connection down to a 3/8 inch female NPT port. It is used to adapt between two different pipe thread sizes in low-pressure fluid and gas systems. The threaded MNPT x FNPT end configuration allows for direct installation into tapped fittings, valves, manifolds, and pipe assemblies without additional adapters. Plumbers, pipefitters, and HVAC technicians install this fitting in both new construction and retrofit applications where a pipe thread size reduction is required.

This bushing is suited for residential and light commercial plumbing, hydronic heating, compressed air distribution, and general fluid handling systems where a 1/2 inch to 3/8 inch NPT reduction is needed. The brass construction provides corrosion resistance and reliable sealing when used with appropriate thread sealant or PTFE tape on the male threads. Class 125 pressure rating makes it appropriate for standard service-pressure pipework encountered in typical trade installations.

Key Features

• Reduces 1/2 inch MNPT to 3/8 inch FNPT in a single fitting
• Class 125 pressure rating for standard service applications
• Threaded end connections for tool-installable, no-solder assembly
• Brass construction offers corrosion resistance in water and air service
• Compact bushing profile fits directly into fittings, valves, and manifold ports

Compatibility

Designed as an OEM-style replacement or installation fitting for any system requiring a threaded 1/2 inch MNPT to 3/8 inch FNPT pipe size reduction in Class 125 service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and IFGC code requirements for the specific service fluid. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply thread sealant or PTFE tape to the male threads before assembly. Do not overtighten brass fittings, as the material is softer than iron and can be damaged by excessive torque.
