Prevent leaks on a barb connection?

[Daasmo]

I'm using a hang on UV light on my AIO. I recently took it off because it was leaking. How can I better seal a tubing to barb connection? Should I be using different tubing?

Cable ties work well to hold connections together and prevent them slipping off.

You need to make sure you are using the correct size tubing for the barb, it should be tight and normally you have to heat the tube to get it over the barb.

Ok. It may be too large then. I can put it on by hand without heating. It is snug but obviously still leaking.

A cable tie or hose clamp may fix it, but really it should not leak without one.

You clamp tight behind the barb.

Hose clamp may introduce rust and metals, I’d say use a zip tie or other nonmetal material

I have plastic clamps. I bought a more flexible tubing. Thanks for everyone for the suggestions.
