Merit Brass NLBS115-0806 Brass Pipe Bushing 1/2x3/8 Mnpt Fnpt

Product Description

The MERIT BRASS NLBS115-0806 is a lead-free brass pipe bushing designed to reduce a 1/2-inch male NPT connection down to a 3/8-inch female NPT port. It is a standard hex bushing used in low-pressure fluid and gas piping systems across plumbing, HVAC, and light industrial applications. Rated at 125 psi and manufactured to Class 125 specifications, this bushing provides a reliable, code-compliant transition between two different pipe sizes. Its lead-free brass construction meets regulatory requirements for potable water service. Plumbers, pipefitters, and HVAC technicians keep these fittings on hand for routine pipe assembly and repair work.

This bushing is suited for residential and light commercial installations where a 1/2-inch to 3/8-inch pipe size reduction is needed. Common applications include supply line transitions, fixture connections, valve installations, and equipment hookups in water, air, and compatible gas systems. The MNPT x FNPT configuration threads directly into standard NPT pipe systems without additional adapters.

Key Features

• Lead-free brass construction meets potable water compliance requirements
• Class 125 rated to 125 psi for reliable low-pressure service
• MNPT x FNPT end connections for direct NPT thread engagement
• 1/2-inch male inlet to 3/8-inch female outlet for straightforward pipe reduction
• Compact hex body for wrench access in tight spaces

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1/2-inch to 3/8-inch NPT pipe reduction applications in residential and light commercial plumbing and HVAC piping systems.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable local plumbing codes and IFGC requirements where gas service applies. Shut off the water or gas supply and depressurize the line before threading the bushing into place. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque brass fittings, as the material can crack under excessive force.
