Merit Brass 3612D-0802 Pipe Reducer 1/2 X 1/8 Inch Fnpt

Product Description

The MERIT BRASS 3612D-0802 is a threaded pipe reducer fitting designed for reducing from a 1/2-inch female NPT connection down to a 1/8-inch female NPT connection. Machined from 316/316L stainless steel, this fitting delivers a pressure rating of 3,000 psi, making it suited for demanding fluid and gas handling applications. At 1-11/16 inches in length and weighing 0.44 pounds, it is a compact, heavy-duty component. Licensed plumbers, pipefitters, and mechanical contractors typically install this type of fitting in process piping, instrumentation, and high-pressure service lines.

This reducer is used in residential and commercial piping systems where a reduction in pipe size is required between two female-threaded ports. Its 316/316L stainless steel construction makes it appropriate for corrosive environments, including chemical processing, marine, and food-grade applications. The FNPT x FNPT configuration suits standard NPT-threaded pipe and fittings commonly encountered in instrumentation, hydraulic, and pneumatic systems.

Key Features

• 316/316L stainless steel construction for corrosion resistance in demanding service environments
• 3,000 psi pressure rating for high-pressure fluid and gas applications
• FNPT x FNPT threaded end connections for straightforward installation with standard NPT pipe
• Compact length of 1-11/16 inches for use in tight installation spaces
• Reduces from 1/2-inch to 1/8-inch pipe size in a single fitting

Compatibility

Designed as an OEM-style threaded pipe reducer for use in standard NPT piping systems requiring a 1/2-inch to 1/8-inch reduction with female connections on both ends.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or ASME B31.3 for process piping. Depressurize and isolate the line completely before disassembling or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads being engaged into this fitting. Do not overtighten, as stainless steel threads are susceptible to galling.
