The 5/8"dia. copper elbow that was soldered to the 5/8" dia. Copper tubing sprung hole in it. I went to a plumming store for a solution to he problem an he sold me a 5/8" dia. Steel elbow with the ferrules to use. It seems too heavy to me o use. Is this combination okay?

Sounds like you have a compression fitting and that should work. Can you post a picture of what you have? There will be an expert along for more help. Hang tight.

Sounds like a compression fitting to me, too guys (see image)! If the copper tubing and fitting are rigid and hard to move you may also need a compression coupling or two!

I would, however, think a SHARKBITE or GATORBITE push on type fitting would be a better set up here, but you did not say what the copper tube goes too, Rudolph??

Agree. Is this a concealed location? Are we really talking 5/8". Or are we talking 1/2" which measures 5/8 on the outside?

Why not use cooper, simple enough and any plumbing supply shop wuld have the correct part. Steel and copper plumbing parts can't touch so is this a dielectric fiiting or what

Use a brass elbow.

It is so simple, unsweat the old elbow, clean off the old solder and sweat the new elbow. Cheaper than brass.
