Description
Midland Copper Male Fitting Adapter - FTG x MPT
Midland Copper Male Fitting Adapters provide a transition from a copper fitting-end connection to a male pipe thread connection. These adapters combine an FTG solder-joint connection with MPT male pipe thread for connecting compatible copper fittings to threaded valves, equipment, fittings, and other piping components.
This listing includes configurations from 1/2" through 2", including a 1/2" x 3/4" option for applications where the copper fitting connection and male pipe thread differ in size.

What Does FTG x MPT Mean?
FTG x MPT identifies the two different connection styles used on this adapter.
- FTG: copper fitting end designed to insert into a compatible copper fitting socket
- MPT: male pipe thread designed to connect to a compatible female threaded component
- Provides a straight copper-to-threaded transition
- Useful when installation space favors a fitting-end connection rather than a cup connection
FTG End vs. Copper Cup
FTG Connection
The fitting end is designed to insert into a compatible copper fitting socket. It does not receive copper tubing directly like a standard cup connection.
Cup Connection
A cup-style connection is designed to receive compatible copper tubing. Copper cup x MPT adapters are maintained as a separate product family.
Why Use an FTG x MPT Adapter?
Compact Connection
The fitting end can insert directly into another compatible copper fitting for a compact transition.
Threaded Equipment Connection
The male pipe thread provides a connection for compatible female-threaded valves, fittings, equipment ports, and accessories.
Copper-to-Thread Transition
Combines a copper solder-joint fitting connection and male threaded outlet in one component.

1/2" x 3/4" Adapter
Part number 77332 provides a 1/2" copper fitting connection with a 3/4" male pipe thread connection.
Solder Joint & Threaded Installation
- Verify both connection sizes before installation.
- Confirm the FTG end will mate with the intended copper fitting socket.
- Clean all copper mating surfaces thoroughly.
- Use soldering materials appropriate for the piping application.
- Protect the male threads from solder, flux, and excessive heat.
- Allow the soldered connection to cool before completing the threaded assembly where practical.
- Use thread sealant appropriate for the piping system.
- Avoid excessive torque on the threaded connection.
