How to get the little collar over the tubing? Tight fit.

Fresh from the factory the fit is generally snug but fine. Bumps and dents in the store can put the tubing out of round a bit but my guess is a tubing cutter was used and that sqeezes the tip, it needs to be reamed. If you used a cutter the reamer is the small triangular thing that sticks out of the side of most cutter. Shop tubing cutter at Lowes.com

When you heat the collar it expands.
You then slide it over the tubing.
It then cools and contracts, giving you a tight seal.

Feroluce...

Are you suggesting they heat the union fitting first, let it cool and then install it to the tubing? If so, that is not the way it is done, OK?

Balengerb1 covered installation very well.

Any questions, let us know...

By the term "copper tubing" do you mean hard copper pipe or soft copper tubing? Back to you, Tom

Massplumber,
No that isn't what I was suggesting, What I was suggesting is what I said, I find communication works better that way.

Mark,
I think he was suggesting heating the ferrule and slipping it over the tubing.

What I was suggesting is what I said, I find communication works better that way.

Kind of snooty in his reply but how would that ever work on a Piece of out of round copper? Doesn't make much sense to me and running copper water pipe was the phase of plumbing that I liked best, Regards, Tom
