I purchased this item to replace another just like it that I thought was worn out...the tubing would slip through the vise part of the tool instead of getting a flare, the tool just pushed the tubing out. Well, the new one came, and while looking at the instructions, I noticed it could be adjusted. I adjusted the old one, and it's working great again. An excellent product which takes the trouble out of making a good flare. One tool does it all, no more 3 piece flare kit for me. I recommend this product for anyone who needs to make flares. I'm in the HVAC business, so mine gets lots of use. Now I have a new back up tool in case the old one breaks.
