Merit Brass 3612D-1604 Pipe Reducer 1x1/4 Ss Fnpt 3000psi

Product Description

The MERIT BRASS 3612D-1604 is a threaded pipe reducer fitting designed to transition from a 1-inch female NPT connection down to a 1/4-inch female NPT connection. Constructed from 316/316L stainless steel, it is rated for service up to 3,000 psi and measures 2-25/64 inches in length. This fitting is well suited for high-pressure piping systems in industrial, commercial, and mechanical applications where corrosion resistance and pressure integrity are critical. Installation is typically performed by licensed plumbers, pipefitters, or mechanical contractors working within applicable piping codes.

This reducer is used wherever a piping system requires a reduction from a 1-inch line to a 1/4-inch branch or instrument connection. Common applications include hydraulic and pneumatic systems, process piping, instrumentation lines, and chemical handling systems where 316/316L stainless steel is specified for corrosion resistance against chlorides and other aggressive media. The FNPT x FNPT configuration makes it a direct threaded connection requiring no special tooling beyond standard pipe wrenches and NPT thread sealant.

Key Features

• 316/316L stainless steel construction for superior corrosion resistance in harsh environments
• Rated to 3,000 psi for high-pressure piping and instrumentation service
• FNPT x FNPT end connections for standard threaded pipe assembly
• Reduces from 1-inch to 1/4-inch for branch or instrument tap transitions
• Compact 2-25/64-inch body length suits tight installation spaces

Compatibility

Designed as an OEM-style threaded pipe reducer compatible with standard NPT piping systems requiring a 1-inch to 1/4-inch female-to-female threaded reduction in 316/316L stainless steel at up to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and piping codes. Depressurize and isolate the system completely before installing or removing any threaded fittings. Apply an appropriate PTFE tape or NPT-rated thread sealant to the male threads mating into this fitting. Do not over-torque stainless steel threaded fittings, as galling can damage threads and compromise the seal.
