Merit Brass K412-1602 Pipe Reducer 1x1/8 Inch Fnpt 150 Psi

Product Description

The MERIT BRASS K412-1602 is a threaded pipe reducer fitting manufactured from 304 stainless steel. It connects a 1-inch female NPT port to a 1/8-inch female NPT port, reducing line size in a single fitting. Rated to 150 psi and conforming to ISO standards, this reducer is suited for plumbing, instrumentation, and light industrial piping systems where corrosion resistance and reliable thread engagement are required. At 0.3 pounds and 1-11/16 inches in length, it is compact enough for tight installations. Plumbers and pipefitters install this type of fitting when transitioning from a larger main line to a smaller branch or instrument port.

This reducer is used in residential and commercial piping systems where a size transition from 1 inch to 1/8 inch is needed along a threaded run. Typical applications include water supply lines, compressed air distribution, hydraulic instrumentation taps, and chemical-handling systems that benefit from 304 stainless steel corrosion resistance. The FNPT x FNPT configuration accepts standard tapered pipe threads on both ends, making it compatible with common threaded pipe and fittings found in trade plumbing and mechanical work.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical environments
• 150 psi pressure rating suitable for low-to-medium pressure plumbing and instrumentation lines
• FNPT x FNPT threaded connection on both ends for straightforward installation with standard pipe thread
• ISO-conforming standards for dimensional consistency
• Compact 1-11/16-inch body length fits confined spaces
• Lightweight at 0.3 pounds for easy handling during installation

Compatibility

Designed as an OEM-style threaded pipe reducer for use with standard 1-inch and 1/8-inch NPT threaded pipe systems in plumbing, mechanical, and light industrial applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local mechanical code requirements. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant tape or compound to the male threads mating to these FNPT ports before assembly. Do not overtighten; use a pipe wrench with a backup wrench to avoid stressing adjacent fittings or pipe.
