Default Immersion Chiller Leaks?

No matter how tight I try to clamp down the hoses to the copper it seems to leak! And when I tighten them as much as possible they slip and strip out. I was hoping to go the quick route and have the clear plastic tubing clamp onto the barbed hose fittings but for the life of me I can't see how others keep a tight seal.

Thanks for any advice, I couldnt find the weld on hose fittings at Lowes?

Do you have the hose shoved on the IC as far as it will go? My IC came with two clamps for each hose. Also, you might want to look into getting new clamps if the ones you have are stripping out when you tighten them down.

I've had problems before with clamps on barbed fittings starting to leak when I put clamps on them. I'm actually going to see if I can get one of the fittings that isn't fully barbed but just has a smooth hump in the middle.

I had the same problem when I purchased my used IC. I ended up buying some heavy duty tubing and two brand new clamps per connection (stripped a couple in the process).
That worked for me.
The other thing that I had considered was using silicone to coat the IC ends just before I pushed the tubing on. I never did do that but thought that it may help?

At work, this is the best that I can do...

It is just braided pvc tubing... you can pick it up at any hardware store.
Hope it that helps.

I've had problems with the cheap hose that came with mine, namely it melts as it rests againts the pot while submerged during boiling, it doesn't melt enough to leak but it gets flattened out from being so soft and causes too much pressure. Replace the crappy hoses with high-temp hose used for pumping hot wort out of kettles.

Are the high-temp hoses just the reinforced ones Lowe's sells?

Or do I have to look for something else?

I'm wondering because the output hose of my wort chiller usually gets really soft and wants to slip off during use. It could use replacing with something that stayed stiff.

I just replaced the hose on my chiller with silicone hose which should not have the issue with softening at high temps. The leaking problems I had with braided PVC were definitely due to high temps; I would leak test with no leaks, but it would leak like mad when turning it on after submerging the coil in the boil to sanitize it. I am also going to two clamps. Hopefully my problems will be coming to an end.

This may work better for you.

Chiller copper tubing to compression fitting:

Then to barbed adapter:

You can hose clamp the tubing to the barb for a better seal. be sure and use teflon tape between the compression fitting and barbed adapter.

I have a brass compression fitting on mine, no leaks there. I've never seen compression fittings with barbs on the other end, but you could screw on a barbed fitting. Don't know if that's clear - my fitting has a compression on one side and pipe thread on the other - I screw an air hose fitting to the pipe thread - but you could buy a pipe to barbed fitting and slip your hose on the barb. Price? comp/brass = $4.49 @ACE - pipe/barb = $2

No I don't cool with air - my air hose fittings are what I use for quick disconnect water fittings. Only problem is the locking balls in the female sometimes rust (cuz they're cheap HFT connectors).

(I guess I'm slow, now there's a picture in the Baron's post)
