Merit Brass 3612D-3220 Pipe Reducer 2x1-1/4 in 316SS Fnpt

Product Description

The MERIT BRASS 3612D-3220 is a threaded pipe reducer fitting machined from 316/316L stainless steel for demanding industrial and commercial piping systems. It transitions a 2-inch pipe down to a 1-1/4-inch pipe using female NPT connections on both ends. Rated to 3,000 psi, this reducer is built for high-pressure service in corrosive or wet environments where carbon steel fittings are not suitable. At 3-3/8 inches in length and weighing 4.93 pounds, it is a heavy-duty forged-class fitting. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.

This reducer is well-suited for process piping, chemical lines, compressed-gas distribution, steam headers, and marine or offshore plumbing applications where 316/316L stainless is specified for its elevated corrosion resistance and chloride tolerance. It is appropriate for both residential and commercial mechanical rooms wherever a code-compliant, high-pressure threaded reduction is required between 2-inch and 1-1/4-inch pipe runs.

Key Features

• 316/316L dual-grade stainless steel construction for superior corrosion resistance in harsh and chloride-rich environments
• 3,000 psi pressure rating suitable for high-pressure piping systems
• Female NPT on both ends for standard threaded pipe assembly without adapters
• Reduces 2-inch pipe to 1-1/4-inch pipe in a single fitting
• 3-3/8-inch body length provides adequate thread engagement and fitting integrity

Compatibility

Designed as an OEM-style threaded pipe fitting for use with standard 2-inch and 1-1/4-inch NPT-threaded pipe in 3,000 psi-rated stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Depressurize and drain the system completely before removing or installing any threaded fitting. Apply a suitable thread sealant or PTFE tape rated for the service fluid and pressure before making up the joint. Do not over-torque threaded stainless fittings, as galling can occur; use appropriate anti-seize compound and hand-tighten before applying wrench torque.
