Merit Brass K614-2002 Pipe Bushing 316 Ss Mnpt Fnpt

Product Description

The MERIT BRASS K614-2002 is a hex pipe bushing machined from 316 stainless steel, designed to reduce a 1-1/4 inch male NPT fitting down to a 1/8 inch female NPT port. At 1-3/16 inches in length and rated for 150 psi, this bushing handles the mechanical and corrosion demands common in plumbing, process piping, and fluid-handling systems where standard carbon steel fittings are not suitable. Licensed plumbers and pipefitters install this type of reducing bushing when transitioning between pipe sizes within a threaded system. The 316 stainless steel alloy provides strong resistance to chlorides and mild acids, making it appropriate for marine, chemical, and food-service environments.

This bushing fits residential and light commercial plumbing systems as well as industrial process lines where a threaded size reduction is needed without adding an additional coupling or nipple. Common applications include instrument ports, gauge connections, drain taps, and branch line reductions. Its male NPT outer thread engages a larger female-threaded fitting or valve body, while the female NPT inner thread accepts a smaller male-threaded pipe, nipple, or instrument connection. The 150 psi pressure rating covers most low-pressure water, air, and compatible fluid service applications.

Key Features

• 316 stainless steel construction resists corrosion in wet, chloride-rich, and mildly acidic environments
• Reduces 1-1/4 inch MNPT to 1/8 inch FNPT in a single fitting
• 150 psi pressure rating suitable for low-pressure water, air, and compatible fluid service
• 1-3/16 inch overall length keeps the assembly compact in tight piping layouts
• Standard NPT threads ensure compatibility with common threaded pipe and fittings

Compatibility

Designed as an OEM-style threaded reducing bushing for use in any standard 1-1/4 inch female NPT port requiring a 1/8 inch male NPT outlet, across residential, commercial, and light industrial threaded pipe systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and local plumbing codes. Shut off and depressurize the line before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-torque stainless steel fittings, as galling of the threads can occur if driven without lubrication or proper thread preparation.
