Merit Brass XNL112-0806 Pipe Reducer Coupling 1/2x3/8 Fnpt

Product Description

The MERIT BRASS XNL112-0806 is a pipe reducer coupling designed to transition between 1/2-inch and 3/8-inch nominal pipe sizes in threaded piping systems. It features female NPT (FNPT) ends on both sides, allowing for a secure, leak-resistant connection between two different pipe diameters. Rated at 125 lb, this fitting is manufactured from brass with a rough finish. It is suited for plumbing, HVAC, gas distribution, and general fluid handling applications where a reliable threaded reduction is required. Licensed plumbers and HVAC technicians are the primary installers of this type of fitting.

This reducer coupling is appropriate for use in residential and light commercial piping systems. It is commonly installed in water supply lines, gas lines rated for brass fittings, and compressed air systems where a step-down from 1/2-inch to 3/8-inch nominal pipe is needed. The FNPT thread pattern is standard throughout North American plumbing and HVAC installations, making this fitting broadly applicable across a wide range of service scenarios.

Key Features

• Transitions 1/2-inch nominal pipe to 3/8-inch nominal pipe in a single fitting
• Female NPT (FNPT) threads on both ends for standard threaded connections
• 125 lb pressure class brass construction for durability in fluid and gas service
• Rough brass finish suitable for functional installations where appearance is secondary
• Compact reducer coupling profile for use in tight pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2-inch by 3/8-inch nominal FNPT threaded piping systems in residential and commercial plumbing and HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads mating with this fitting. Do not over-tighten brass fittings, as excessive force can crack or distort the fitting body.
