The first ridgid set we had worked very well and never had trouble with it until it grew legs and left our shop. The replacement never worked very well on the small sizes like 1/2" & 3/8". It would crack the tube 70-80% of the time no matter what we did. Well now I don't have to worry about that tool anymore cause it grew legs just like the first one. Now we're looking for another replacement and will probably go with the Ridgid. But...
A lesson Learned--put a big chain around its neck.
I've got a no-name swage/flare kit I bought 15 years ago and it is still going strong. Didn't have a name but it is similar to the IMPERIAL set and works from 1/4" up to 3/4" OD tubing. I have found that on any tubing less than 3/8"OD the swage is nasty so, I use the hammer in types with no problems. I bought the precursor to the RITCHIE bender set 3 years ago and I haven't had to stock any fittings other than threaded ones, don't have taps or dies to cut flare threads. If you get a good one you will bless your lucky stars!
