Eaton 3200X8X6 Pipe Adapter 3/8 Male X 1/2 Female Mnptf

Product Description

The EATON 3200X8X6 is a straight pipe thread adapter designed to connect a 3/8-inch male NPT fitting thread (MNPTF) to a 1/2-inch female NPT fitting thread (FNPTF). It is used to reduce or transition between two different thread sizes within a pressurized fluid or gas line. Rated to 1,200 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this adapter is built for demanding industrial and trade applications. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during system assembly, maintenance, or retrofits where thread size changes are required in the line.

This adapter suits straight-run piping configurations in residential, commercial, and light industrial systems. It is appropriate for use in hydraulic lines, pneumatic systems, fuel lines, and general-purpose fluid transfer applications where MNPTF-to-FNPTF thread conversion is needed. The straight fitting shape allows for in-line installation without directional change. Its 1-1/16-inch hex size accommodates standard wrench engagement, and the overall length of 1-1/2 inches keeps the inline profile compact in tight installations.

Key Features

• Reduces from 1/2-inch female NPT thread to 3/8-inch male NPT thread in a straight configuration
• Rated to 1,200 psi maximum working pressure
• Operating temperature range of -65 degrees F to 250 degrees F
• 1-1/16-inch hex size for standard wrench or plier engagement
• Overall length of 1-1/2 inches for compact inline fitment
• Meets ASA, ASME, and SAE 130139 standards

Compatibility

Designed as a standard OEM-style pipe thread adapter for pressurized fluid and gas systems requiring a straight MNPTF x FNPTF thread transition between 3/8-inch male and 1/2-inch female NPT connections.

Installation Notes

This fitting is typically installed by licensed plumbers, pipefitters, or HVAC technicians. Shut off system pressure and depressurize the line completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads in accordance with the system fluid or gas type and applicable code requirements such as ASME B31.1 or IFGC. Do not overtighten tapered NPT threads, as this can crack fittings or distort the thread engagement.
