Review on Stainless Adjustable Automotive Mechanical Applications by Mark Adlesh

These clamps are terrible! Any light pressure, I'm talking 5-7 pounds of pressure on a pull, and it'll snap the worm gears off. The first 3 I tried out of the pack did the trick. I've used for coolant lines so I needed a tight fit and it didn't work out very well. I suggest using a different clamp than this one if you need an airtight seal.
