Merit Brass K612-2406 Pipe Reducer 1-1/2x3/8 Fnpt 316 Ss

Product Description

The MERIT BRASS K612-2406 is a threaded pipe reducer fitting designed to transition between a 1-1/2 inch female NPT inlet and a 3/8 inch female NPT outlet. Constructed from 316 stainless steel, it delivers strong resistance to corrosion and oxidation, making it well-suited for demanding fluid and gas piping applications. The fitting carries a 150 psi pressure rating and is manufactured to ISO standards. At 2-1/16 inches in length and 0.58 pounds, it is a compact, durable component installed by licensed plumbers and pipefitters in both commercial and industrial systems.

This reducer is used in piping systems that require a step-down in line size while maintaining a fully threaded connection throughout. Typical applications include process piping, chemical handling, food-service plumbing, marine installations, and any environment where corrosion resistance is a priority. The FNPT x FNPT configuration allows direct thread engagement on both ends, simplifying installation in tight or confined spaces where welded or flanged fittings are not practical.

Key Features

• 316 stainless steel construction for superior corrosion and oxidation resistance
• FNPT x FNPT threaded ends for straightforward pipe engagement on both sides
• 150 psi pressure rating suitable for low-to-medium pressure piping systems
• ISO standard compliance for consistent dimensional and performance requirements
• Compact 2-1/16 inch length fits confined piping runs and tight equipment connections
• Reduces line size from 1-1/2 inch to 3/8 inch in a single fitting

Compatibility

Designed as an OEM-style threaded pipe reducer for use in standard NPT piping systems rated at 150 psi or below where 316 stainless steel material is specified.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply a compatible thread sealant or PTFE tape to the male threads before engagement, and hand-tighten before using a pipe wrench to complete the connection. Do not over-torque, as stainless steel threads can gall if excessive force is applied.
