Merit Brass K612-1602 Pipe Reducer 1x1/8 in 316 Ss

Product Description

The MERIT BRASS K612-1602 is a threaded pipe reducer fitting designed to connect piping of two different diameters in a single inline transition. It reduces from a 1-inch female NPT inlet to a 1/8-inch female NPT outlet, making it suitable for gas, water, and fluid piping systems that require a controlled size reduction without an external coupling or bushing. Constructed from 316 stainless steel, this fitting resists corrosion in aggressive environments including those with exposure to chlorides or chemical vapors. It carries a 150 psi pressure rating and measures 1-11/16 inches in length. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.

This reducer fitting is used in residential and light commercial plumbing, HVAC, and fluid handling applications where a straight inline pipe size reduction is required. Its FNPT x FNPT end connections allow it to thread directly onto standard NPT male pipe ends on both the supply and receiving sides of the connection. The 316 stainless steel construction makes it a preferred choice in installations exposed to moisture, salt air, or mild chemical environments, such as marine, food service, and industrial support systems.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• FNPT x FNPT end connections for standard NPT threaded pipe on both sides
• Rated to 150 psi for use in low-to-medium pressure fluid and gas systems
• Inline reducer design transitions from 1-inch pipe to 1/8-inch pipe in a single fitting
• Compact 1-11/16-inch body length minimizes space requirements in tight assemblies

Compatibility

Designed as an OEM-style replacement or new-install threaded pipe reducer for standard NPT piping systems requiring a 1 x 1/8-inch inline reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-tighten, as stainless steel threads can gall if excessive torque is applied.
