Does anyone know what the fitting is that joins the three smaller tubes of the King Cobra to the large tube?
Is it generally available do you think, or has it been specially made?

Can I guess you are thinking of building?

If so.... you could use 15mm feed pipe into 10mm twin coils. The fittings are easy to get and 10mm rolls very nicely.

I did. 90c > 20c in 6 or 7 mins.

Used the Hydra for the first time yesterday cooled 25ltrs of wort down from 100c to 22c in around 13-15 minutes.
I think I can inprove on that time with some cooler water.
Which is a huge improvment on the Speidel coil.

OK - an old thread but I am looking for an IC rather than my plate chiller for the obvious simplicity.
I like the bullet proof nature of stainless but surely copper must be better so I found myself looking at the Hydra, looks like a good fit for the BM20.

Nashbrew - I see you have managed to get hozelock fittings on there - was that straightforward? I have managed it onto 1/2" NPT without issue using a 1/2" to 3/4" BSP adapter. What was your route. I must confess to severe irritation with stacks of thread adapters but it's just cooling water. I could go the Mashy route but I like the look of rigidity and "neatness" of the Jaded stuff even if it does mean nooks and crannies that are harder to clean.

I'm hoping to convince a US colleague to take delivery for me, doubt he'll want to bring it over in checked luggage though!

Oh no, dreaming of more shiny.....

Make one. The sense of achievement is cracking. Copper is easy to buy and bend.

OK part of me likes the idea of diy but another part of me just wants a no hassle does what it says on the tin solution. Curiously, mentally, the decider might be the connector path!

Apologies - I'm a little OCD over chains of adapters ("can anyone be a bit OCD?" -ER)

Connector path. US chillers are usually set up to use US hose thread (GHT). UK hozelock / Gardena fittings (pretty much standard) use 3/4" BSP, the same as on a garden tap. I have an adapter to this thread on my utility room mixer tap so I can mount Hozelock fittings onto it.

So to attach a hozelock fitting to a US chiller means you either need a length of hose with a friendly connector on either end, this is what I use for my plate chiller, or else a nightmare of various adapters to get from GHT to 3/4" BSP - usually this involves one thread that "almost" works given some packing washers and screwing it on until the thread is almost crossed (like that bottle cleaning gizmo that almost fits onto a tap).

This is made worse by the fact that jaded use a male and a female GHT.

One handy combination is that male 1/2" pipe thread (NPT) that is common in US brewing stuff seems to fit 1/2" BSP - this means that little adapter you get with hozelock tap fittings fits it and you can neatly step up to 3/4" BSP. I note the fact that the king Cobra allegedly uses a male 1/2" NPT before the GHT connectors - this could be great.

My view is that if I had to have some nightmare chain of thread adapters that leaks and sticks out the "sub optimality" will be worse than the inevitable mishapen coil I'd get if I made one myself.
I did warn you I was a bit OCD on this!
Of course that would mean I'd first have to build myself a shed in which to build the chiller ............... looking cheaper to buy one, though the shed might come in handy for other things and would get my brew stuff out of the utility room :-)

Interesting MrMalty link.

plus I also notice that Jaded has male and female GHT hose barbs on their site :-)
I should have better things to think about on a Sunday!

Hi jamesmb

The picture shows a tempary solution
I am in the UK so I had to convert to 3/4"BSP.
Cleaning has not been an issue and the cool down time is a completly different story compared to a speidel.
I removed the US fittings first.Warning they are bonded with some sort of thread glue.

I bought 2 of these:
