Copper Flush Bushing 1/2 x 3/8

This copper flush bushing connects a 1/2 inch FTG fitting to a 3/8 inch copper tube. It is designed for sweat soldering in plumbing installations. The wrought copper construction suits potable water, air and gas lines. Professional plumbers and DIY installers use it to reduce pipe diameter at a joint.

Suited For Sweat Solder Joints

This bushing suits installers making permanent sweat connections in copper systems. It is not for threaded, compression or press-fit joining methods. Builders needing a reducing coupling with two cup ends should select a different fitting. Projects requiring larger or smaller nominal sizes need alternative components.

Rated 722 psi at 100 Degrees F

The maximum operating pressure is 722 psi at 100 degrees Fahrenheit. The fitting withstands temperatures up to 400 degrees Fahrenheit. This pressure rating determines whether the bushing meets the demands of a specific water, air or gas distribution system. Always verify system requirements against these limits before installation.

Questions about this item

What pressure does the 1/2 x 3/8 copper flush bushing handle at 100 degrees F?

The fitting is rated for a maximum operating pressure of 722 psi at 100 degrees F.

What tube diameters must the flush bushing connect?

It joins a 5/8 in outer-diameter tube on the fitting side to a 1/2 in outer-diameter tube on the copper side.

How is the flush bushing installed and what step is often missed?

It is a sweat fitting, so clean both tube ends, apply flux, slide the bushing on, then heat evenly with a torch until solder flows; the step often missed is heating the fitting body rather than the tube so the solder wicks into the joint.
