1/2" Heavy Duty Double Gripping Nylon Plastic Hose Clamps, 225° F / 200 PSI Rated, 10 Pack (Made in USA/UK)

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!

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.

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

great clamp but too small for general aquarium set ups. the size is the inside diameter which will be your outside diam of your tubing. negatives is once you clamp it, you will need to cut off the top lock portion of the clamp to take it off.

Durable

Needed something to clamp my air hose and keep the psi. This one is the easiest to install and take off if needed compared to other metal ones

Seem to work well enough. I still like the screw type better.

quality item fits perfect on my tubing. much nicer to look at as well than the metal clamps in my opinion. fast shipping great price cant ask for anymore. thank you for providing this product for people like me.
