Counterflow chiller fixings

[user 40634]

Hi, I recently bought a keg land counterflow chiller from a UK distributor, and watched their video on fixings. The copper ends are 3/8’’ and to attach these to a hose coupling they recommended using duotight fixings (Duo 115: 3/8 x 1/2 inch male). Unfortunately I can’t find anywhere that has stock in the UK. Can anyone advise me on an alternative option as the kit is unusable at present. Thanks in advance

Hi I had a similar issue recently and found that the ends were 10mm not 3/8" despite the video which yes does refer to duo tight. The kegland specification for the chiller states they are 10mm. I ended up using brass compression fittings with the 1/4 to 1/2 adaptor and then brass hoselock connectors, with ptfe tape on all the screw threads.

However, I've since found you can get a 10mm compression to 1/2 BSP thread fitting which would have made the whole thing simpler and a bit cheaper:

EDIT = oops that was the female version - this is the male 1/2" one

I have received the same model as a Xmas present, I have a question in that to achieve the best cooling of the wort do I need to throttle the water exit or the wort exit. The wort will be supplied via the brewzilla’s pump

I don't throttle at all as you'll find that your coil which will be roughly 10m long has plenty of travel for the flow to heat up and be extremely hot on exit but be sure if you have stop valves fitted to leave both ends open when submersing otherwise you will have a pressure build up which could be nasty.
