Questions about this item

Will the U617 cap seal properly on my existing 3/4" copper tube without re-soldering the joint?

The U617 is a wrot copper cap designed for 3/4" tube; it must be soldered onto the pipe end to create a watertight seal, so the existing joint will need re-soldering.

How can I verify the cap is seated correctly after soldering?

After the joint cools, apply water pressure to the line and inspect the solder ring around the 3/4" cap for any moisture or drips indicating a complete seal.
