Merit Brass K612-0802 Pipe Reducer 316 Ss Fnpt 150 Psi

Product Description

The MERIT BRASS K612-0802 is a threaded pipe reducer fitting designed to connect pipes of two different diameters in fluid and gas piping systems. Machined from 316 stainless steel, this fitting offers strong corrosion resistance in demanding environments, including those with exposure to chlorides or caustic media. The fitting uses female NPT (FNPT) connections on both ends, making it a straightforward threaded installation. Rated at 150 psi and conforming to ISO standards, it is well suited for professional plumbing, instrumentation, and process piping applications where material integrity and pressure reliability matter.

This reducer is used in residential and commercial piping systems wherever a 1/2 inch line must transition down to a 1/8 inch connection. Typical applications include instrument take-off points, chemical feed lines, compressed air systems, and process fluid piping. The 316 stainless steel construction makes it a preferred choice in coastal, marine, food service, and industrial environments where 304 SS or carbon steel fittings would be susceptible to corrosion. The compact overall length of 1-23/64 inches suits installations in tight or congested piping runs.

Key Features

• 316 stainless steel construction for superior corrosion resistance over standard 304 SS
• FNPT x FNPT threaded end connections for tool-only installation with no welding required
• 150 psi pressure rating suitable for low-to-moderate pressure service
• ISO-conforming dimensions for consistent fit with compatible threaded fittings
• Compact 1-23/64 inch overall length for use in confined piping spaces
• Reduces a 1/2 inch pipe connection to a 1/8 inch connection in a single fitting

Compatibility

Designed as an OEM-style threaded pipe reducer for use in 150-class FNPT piping systems requiring a 1/2 inch to 1/8 inch reduction in 316 stainless steel.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters in accordance with applicable codes such as the IPC or ASME B31 piping standards. Shut off and depressurize the system completely before removing any existing fitting or installing this reducer. Apply an appropriate thread sealant or PTFE tape to the male threads mating into this fitting; do not over-apply sealant in a way that could contaminate the downstream line. Hand-tighten first, then use a pipe wrench to achieve a snug, leak-free connection without cracking the fitting body.
