Merit Brass 3412D-3208 Pipe Reducer 2x0.5 in Ss Fnpt

Product Description

The MERIT BRASS 3412D-3208 is a stainless steel pipe reducer fitting designed to connect a 2-inch pipe to a 0.5-inch pipe using female NPT threads on both ends. Manufactured from 304 and 304L stainless steel, this reducer delivers a pressure rating of 3,000 psi, making it suitable for demanding fluid and gas distribution applications. The FNPT x FNPT connection style allows direct thread engagement on both sides without additional adapters. Plumbers, pipefitters, and mechanical contractors working on high-pressure systems will find this fitting appropriate for industrial and commercial piping runs where corrosion resistance is required.

This reducer is commonly used in commercial and industrial plumbing, HVAC piping systems, and process fluid lines where a significant reduction from a 2-inch line to a 0.5-inch branch or outlet is needed. The 304 and 304L stainless steel construction resists corrosion in wet environments, chemical exposure, and elevated-temperature service conditions. It is suited for installations governed by ASME or ASTM standards for stainless steel fittings in pressure piping systems.

Key Features

• Reduces a 2-inch pipe connection down to a 0.5-inch connection in a single fitting
• Rated to 3,000 psi for high-pressure system compatibility
• Dual-grade 304 and 304L stainless steel construction for corrosion resistance
• FNPT x FNPT end connections for standard threaded pipe installation
• Suitable for fluid and gas distribution piping per UNSPSC code 40175300

Compatibility

Designed as an OEM-style threaded pipe fitting replacement for 2-inch by 0.5-inch FNPT reducer applications in commercial and industrial stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. De-pressurize and drain the system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads engaging these female NPT connections. Do not over-torque the fitting, as stainless steel threads are susceptible to galling.
