These tools work well, better than a wrench or pliers. Sometimes I use two of them back to back to pry against each other. Wish I would have had these years ago.

These work extremely well for what they are designed for. I have fought the "new" style push in air lines for years and would fuss and cuss trying to get them a part. These tools from Lisle make that job almost effortless now. I highly recommend the Lisle 42400 air line disconnect set, I can't believe I waited so long to purchase these.

I deal with poly tubing that are in tight spots to remove with my fingers. These tools save me a huge headache. All you do is get the size that fits over your line and push against it and that's it.
