I have found hardware stores to carry 5/16" PP tubing which is fairly rigid, you an cut them down to the lengths you like. 5/16 is useable with the 8mm fittings.
A slow, mechanical relay based, on/off controller is way less than ideal. For most RIMS tube applications you want a cycle time around 1-2 seconds (as in when cycle time is 1 sec and the controller is calling for 50% you are on for 0.5sec, off for 0.5 sec) and that controller is not fast enough...
Just to clarify on this, for the 20g you will want a bigger heat mat than the one I have listed for the 10g.
Before I had the heater deployed I found it essential to preheat the tun as it is a decently large thermal mass. I just would fill my my wife's electric tea kettle, get the water to a...
Multiple Element RTDs are a thing where you have multiple measuring elements in the same probe that can be hooked up to different devices if you want to go that route. But in my opinion the cheaper option would just be to introduce a second probe running a DS18B20 so that whatever you have...
Liquid nails and ratchet straps. My collar had a bit of warp to it and I held the collar down while the liquid nails was curing with ratchet straps. Once cured the collar stayed flat.
It looks like a center inlet version of this.

Sorry for the double post. I did try that initially. However this fitting blew the tubing all the way out. I think i just fell into a bad range of tolerance stack between the eva barrier tubing and this particular fitting. Of the 5 disconnects I bought only one gave me grief. But it got clips on...
Pardon the late reply. It was my standard west coast IPA recipe. After the failed brew, I made the batch immediately again with a packet of S-05 and it worked flawlessly.
I think these disconnects are fine. My biggest gripe with them is that they don't come with retaining clips from the factory. I lost a 20# CO2 tank and dumped a whole keg of seltzer into my keezer (carbstone dip tube). Because the tube popped out of the connector. So here is a printable clip for...

Your temp probe wires may be damaged and are reading an open circuit to the controller.
It did not treat me well either. I used a satchet on a recipe where I normally use a single pack of s-05. Took forever to start and ended up as hot band aid water.
