Merit Brass 3612D-2412 Pipe Reducer 1-1/2 X 3/4 in Fnpt 3000 Psi

Product Description

The MERIT BRASS 3612D-2412 is a threaded pipe reducer designed for high-pressure piping systems where a reduction from a 1-1/2 inch to a 3/4 inch line is required. Constructed from 316/316L stainless steel, this fitting delivers strong corrosion resistance, making it well suited for aggressive fluid handling, chemical process lines, and marine or coastal installations. Both end connections are female NPT (FNPT), allowing direct thread-in installation with standard NPT male-threaded pipe or fittings. The 3,000 psi pressure rating places this fitting in the Class 3000 forged fitting category, appropriate for demanding process and industrial service applications. Overall length is 3-7/64 inches.

This reducer fitting is used in industrial, commercial, and heavy mechanical piping systems where stainless steel is specified for corrosion resistance or sanitary requirements. Typical applications include process piping, fluid transfer lines, compressed gas systems, and plumbing tie-ins requiring a branch or line reduction. The FNPT x FNPT configuration suits installations where both connecting pipes carry external male threads. Plumbers, pipefitters, and mechanical contractors working to ASME or applicable pressure piping codes commonly install this type of fitting.

Key Features

• 316/316L stainless steel construction for superior corrosion and chloride resistance
• 3,000 psi pressure rating meets Class 3000 forged fitting service requirements
• FNPT x FNPT threaded ends for straightforward thread-in assembly without welding
• Reduces from 1-1/2 inch to 3/4 inch nominal pipe size in a single fitting
• 3-7/64 inch overall length for compact inline installation

Compatibility

Designed as an OEM-style threaded pipe reducer compatible with standard NPT male-threaded pipe and fittings in 1-1/2 inch and 3/4 inch nominal pipe sizes rated for Class 3000 service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable pressure piping codes such as ASME B31.3 or local mechanical code requirements. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid and pressure before threading the fitting into place. Do not over-torque threaded connections, as this can damage threads or cause cracking in the fitting body.
