4 in to 3 in straight reducing coupling

This copper sweat fitting joins a 4 inch tube to a 3 inch tube in a straight line. It handles air, gases and potable water at up to 293 psi at 100 Degrees F and 400 Degrees F maximum temperature.

Installers needing a direct copper-to-copper

Suitable for plumbers and HVAC technicians making a permanent sweat connection between different tube sizes. Not for anyone who requires a threaded, press-fit or push-to-connect joint, or who needs a fitting compatible with non-copper piping systems.

Sweat cup connections on both ends

Both ends are plain cup sockets made for soldering to 4 1/8 in and 3 1/8 in outer diameter copper tube. This joint type requires flux, solder and a torch, so it is unsuitable where open flame is prohibited or where a mechanical joint is specified.

Questions about this item

Does the coupling come with solder or flux, or must I buy them separately?

The fitting is supplied as a single wrot copper reducing coupling; solder, flux and any cleaning tools are not included and must be purchased separately.

Should I choose this 4 in by 3 in straight reducing coupling or a different size for my pipe run?

Select this coupling when you need to join a 4 in copper tube to a 3 in copper tube in a straight line; other diameters or elbow shapes will not fit that transition.

What does the 293 psi rating mean when the fitting is installed in a hot-water system?

The coupling is rated for 293 psi at 100 °F; at higher temperatures up to 400 °F the allowable pressure drops, so design the system accordingly.
