Stainless steel immersion chiller connections

Unread postby mooncat » Sat Nov 03, 2018 4:34 pm

I have the Braumeister so immersion chiller that I connect to hot and cold in and out with quick release garden hose connectors. I’ve had the plastic Hozelock and equivalent types but though they are fine for a while they have shot off unexpectedly. I have tried more expensive metal connectors but got sprayed twice again today! Does anyone have a better compression /screw type connection and what fittings do you use?

The Hozelock Connectors might not be compatible with the Braumeister Gardena-System.
I use those Gardena Hose Connectors with my Stainless Steel Wort Cooler for a very long time.
So far they have never failed.

Always use Hozelock ones on mine and never had any issues at all.
Are all the small plastic hose retainers in place correctly or are a few bent in or missing-sometimes that can happen and the hose will pop off ! :beerbang: :drink:

Hozelocks have always worked for me as well.

Well, an epic fail today! Changed the Hozelock connections, put an extra 4 clips on either end of the silicon tube on the chiller and connect end. Tested for an hour under pressure, all fine. Began cooling with little pressure. Almost as soon as hot water hit the outlet silicone tube it burst! Looks like I’ll go down the compression quick disconnect route now. I’ve been using the chiller for 4 years so looks like tube fatigue.

I think you may have missed whats happening.

When you drop a cold coil into boiling water everything expands - quickly. And the weakest link breaks.

Leave the exit pipe and exit valve open - I think that will solve the problem ...

And do not use silicone tube. It is useless with heat.

Agreed, the ordinary stuff is terribl.

The dairy stuff is good. Platinuim cured. Expensive but worth it.

Somthing like this ...https://www.themaltmiller.co.uk/product ... g-12mm-id/

Thanks for the tips. I did put the chiller in unconnected for ten minutes in the boil to sterilise. I think the tube simply became fatigued over time
