Merit Brass 3614D-1604 Pipe Bushing 1x1/4 Ss Threaded

Product Description

The MERIT BRASS 3614D-1604 is a threaded pipe bushing designed to reduce a 1-inch male pipe thread down to a 1/4-inch female pipe thread in high-pressure piping systems. Constructed from 316/316L stainless steel, this bushing delivers strong corrosion resistance, making it well-suited for demanding fluid and gas handling applications. It carries a pressure rating of 3,000 psi and measures 5/8 inch in length. The MNPT x FNPT connection type allows for direct thread-in installation without additional fittings. Plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this component.

This bushing is used in residential, commercial, and industrial piping systems where a pipe size reduction is needed between threaded connections. Its 316/316L stainless steel construction makes it appropriate for corrosive environments, including chemical processing lines, marine applications, food service piping, and similar services where carbon steel fittings are not suitable. It installs wherever a standard threaded hex bushing is required to transition from a 1-inch pipe to a 1/4-inch pipe port or fitting.

Key Features

• 316/316L stainless steel construction provides corrosion and chemical resistance
• 3,000 psi pressure rating for high-pressure piping service
• MNPT x FNPT threaded end connections for straightforward installation
• Reduces 1-inch male thread to 1/4-inch female thread in a single fitting
• Compact 5/8-inch length minimizes space requirements in tight installations

Compatibility

Designed as an OEM-style threaded pipe bushing for use in standard NPT threaded piping systems requiring a 1-inch to 1/4-inch reduction in 316/316L stainless steel at up to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable plumbing codes such as the IPC or relevant ASME B16 standards. De-pressurize and drain the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Do not over-tighten threaded connections, as this can damage the fitting or the mating thread.
