Merit Brass 3614D-0604 Pipe Bushing 3/8 in Ss 3000 Psi

Product Description

The MERIT BRASS 3614D-0604 is a threaded pipe bushing designed to reduce or adapt pipe connections within pressurized plumbing and piping systems. Constructed from 316/316L stainless steel, it offers strong corrosion resistance in both standard and mildly corrosive service environments. The bushing features a male NPT (MNPT) external thread and a female NPT (FNPT) internal thread, making it a direct-thread adapter for joining pipes or fittings of differing sizes. Rated to 3,000 psi, this fitting is appropriate for high-pressure piping applications. Plumbers, pipefitters, and mechanical contractors install this type of fitting as part of threaded piping assemblies.

This bushing is suited for use in commercial and industrial plumbing systems, process piping, and mechanical systems where a 3/8 inch threaded connection point requires adaptation. The 316/316L stainless steel material grade makes it appropriate for applications where mild chemical exposure or moisture is a concern, such as HVAC condensate piping, water service lines, and light industrial fluid systems. It ships as a single unit and is intended for installation by licensed plumbers or qualified pipefitters working in accordance with applicable plumbing codes.

Key Features

• 316/316L stainless steel construction provides corrosion resistance in wet and mildly chemical service environments
• 3,000 psi pressure rating supports high-pressure threaded piping assemblies
• MNPT x FNPT end connections allow direct threaded installation without additional adapters
• 3/8 inch fitting size fits standard NPT pipe and fitting threads
• Threaded connection type requires no special tooling beyond standard pipe wrenches or strap wrenches

Compatibility

Designed as an OEM-style threaded pipe bushing for use in standard NPT threaded piping systems rated to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with the applicable International Plumbing Code (IPC) or local authority requirements. Depressurize and isolate the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or damage thread engagement.
