Merit Brass 3612D-0602 Pipe Reducer 3/8 X 1/8 Inch Ss

Product Description

The MERIT BRASS 3612D-0602 is a threaded pipe reducer fitting designed to connect a 3/8-inch female NPT port to a 1/8-inch female NPT port in high-pressure piping systems. Constructed from 316/316L stainless steel, it carries a pressure rating of 3,000 psi and measures 1.5 inches in length. The FNPT x FNPT configuration makes it suitable for joining pipes of two different sizes without additional adapters. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in systems where corrosion resistance and pressure integrity are critical requirements.

This reducer is well suited for use in residential and commercial plumbing, process piping, chemical handling lines, and instrumentation systems where 316/316L stainless steel is specified for its superior corrosion resistance. The FNPT x FNPT end connections accept standard NPT male-threaded pipe ends. Typical applications include reducing line size at instrumentation taps, manifold assemblies, and compressed gas or fluid distribution systems operating at elevated pressures.

Key Features

• 316/316L stainless steel construction for excellent corrosion and chemical resistance
• 3,000 psi pressure rating suitable for high-pressure piping applications
• FNPT x FNPT end connections accept standard NPT male-threaded pipe
• Reduces from 3/8-inch to 1/8-inch fitting size in a single fitting
• 1.5-inch overall length for compact inline installation
• Dual-grade 316/316L material meets both standard and low-carbon stainless requirements

Compatibility

Designed as an OEM-style threaded pipe reducer for high-pressure piping systems requiring 3/8-inch to 1/8-inch FNPT connections in 316/316L stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC or relevant local standards. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the fluid service and pressure before making up the connection. Do not over-tighten threaded connections, as this can damage the fitting threads or cause leaks.
