    Not for 1/2 inch size drip tubing!!
  

*by S***N on Reviewed in the United States on April 10, 2022*

I purchased these intended to clamp up 1/2 inch OD drip supply line tubing I connected to a manual valve with barb fitting. To my disappointment, these clamp won't fit, even unto the tubing by itself! I should have read the many reviewers here first, that also experiencing same problem I have. (May work ok for 3/8" tubing, however...). I ended up using the old reliable small hose worm gear metal clamps!

### ⭐ 







  
  
    wont fit 1/2 inch diameter.
  

*by J***F on Reviewed in the United States on November 2, 2020*

Dont they understand that if they were clear and honest about what diameter these will fit that theyd sell twice as many?  Anyway, if youre buying these for 1/2 inch diameter tube then I dont know what to tell you but the cable I wanted to use them on is .5 inches and these are too small.  Theyre also more expensive than the others, which also are completely unclear about what diameters theyll fit, but the price wasnt the problem.  I just needed them to work and having waited for them to arrive Im pretty disappointed and angry that they arent as described.  Now I have to go with the only other alternative (a plastic shaft collar with two screws) and thats 3 times more expensive.

### ⭐⭐⭐⭐⭐ 







  
  
    Works as described
  

*by G***Y on Reviewed in the United States on November 28, 2020*

Worked very well on small hoses and small end Bellows clamp on my Mercruiser stern drive.
