Sweat Fitting Union for Tubing Systems

This sweat fitting union connects two copper tubes in plumbing installations. It suits installers who need a straight copper-to-copper joint with cup connections on both ends. Buyers requiring threaded or compression fittings will not be able to use this part.

3/4 in Cup Connection on Both Sides

Each end accepts a 3/4 inch copper tube with a 7/8 inch outer diameter. The cast copper body handles up to 580 psi at 100 degrees F and temperatures up to 400 degrees F. Systems needing larger tube sizes or different pressure ratings cannot use this union.

Cast Copper Body with No Flange

The straight union shape has no flange, so it fits tight spaces where a flanged fitting would interfere. Installers must solder the cup joints during assembly. Projects requiring a flanged union or a removable mechanical joint will need a different fitting type.
