Merit Brass 3614D-1202 3/4 in Ss Pipe Bushing Mnpt X Fnpt

Product Description

The MERIT BRASS 3614D-1202 is a threaded pipe bushing designed to reduce or adapt pipe thread sizes within pressurized piping systems. Constructed from 316 and 316L stainless steel, it delivers strong corrosion resistance in demanding environments including chemical exposure, saltwater, and high-moisture installations. The bushing features male NPT (MNPT) on the outer thread and female NPT (FNPT) on the inner thread, with a pressure rating of 3,000 psi and an overall length of 0.625 inches. Licensed plumbers and pipefitters install this fitting in commercial and industrial piping assemblies where corrosion-resistant metallic components are required.

This bushing is suited for use in plumbing, HVAC piping, and industrial fluid handling systems where 316 or 316L stainless steel is specified for corrosion resistance. It fits into standard NPT-threaded piping configurations at the 3/4 inch fitting size. Typical applications include process piping, marine installations, chemical handling lines, and food-service or sanitary systems where stainless steel is a material requirement. Its compact length makes it appropriate for tight-clearance fittings and close-coupled connections.

Key Features

• 316 and 316L stainless steel construction for superior corrosion and chloride resistance
• 3,000 psi pressure rating suitable for high-pressure piping applications
• MNPT x FNPT threaded end connections for standard NPT pipe assembly
• 3/4 inch fitting size for common pipe thread configurations
• Compact 0.625 inch length for use in tight-clearance installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 3/4 inch NPT-threaded piping systems requiring 316 or 316L stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or ASME B31 piping standards. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service media and pressure. Do not overtighten threaded connections, as stainless steel threads can gall if excessive torque is applied without proper lubricant or sealant.
