Merit Brass 3612D-2406 Pipe Reducer 1-1/2 X 3/8 in Fnpt 3000 Psi

Product Description

The MERIT BRASS 3612D-2406 is a threaded pipe reducer fitting machined from 316/316L stainless steel for corrosion-resistant performance in demanding piping systems. It reduces a 1-1/2 inch female NPT connection down to a 3/8 inch female NPT connection, making it a direct inline reducer for piping runs that require a step-down in pipe size without a change in fitting type. Rated to 3,000 psi, this fitting is suited for high-pressure service in plumbing, process, and industrial applications. Overall length is 3-7/64 inches. Licensed plumbers and pipefitters are the typical installers for this class of fitting.

This reducer is used in residential and commercial piping systems where a size transition between 1-1/2 inch and 3/8 inch pipe lines is required. Common applications include process fluid lines, compressed air systems, hydraulic lines, and general plumbing distribution headers where stainless steel construction is specified for corrosion resistance or sanitary requirements. The FNPT x FNPT end connections accept standard tapered pipe threads on both ends.

Key Features

• 316/316L stainless steel construction for superior corrosion resistance in wet, chemical, and marine environments
• 3,000 psi pressure rating suitable for high-pressure piping service
• FNPT x FNPT end connections accept standard tapered pipe threads on both ends
• Reduces 1-1/2 inch to 3/8 inch in a single inline fitting
• 3-7/64 inch overall length for compact installation

Compatibility

Designed as an OEM-style threaded reducer for use in standard NPT piping systems requiring a 1-1/2 inch to 3/8 inch size reduction in stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or ASME B31 piping code requirements. Depressurize and isolate the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before making up the connection. Do not over-torque stainless steel threaded fittings, as galling can occur.
