Tube and stuff

[taylorj29]

I'm thinking of using John Guest conduit as the lines between the HLT, MLT etc. because I want to use push-fit taps instead of costly valved quick connects. Has anyone had any experience of using the pipe in this application ?

I doubt that the plastic john guest will survive temperatures 50c + unless you are refering to the larger central heating style ones in which case I am not sure they are food safe. Would be interested to know peoples opinions however.

 

[taylorj29]

It's temp rated to 114c but I forgot about the food grade thing D'oh

Oh well, back to the drawing board :hmm:

If you are brewing for yourself then there really isn't a worry about the food grade aspect is there?

It's all the same stuff at the end of the day, just with less testing overhead...?

(Kind of like the whole PIP implant silicone - same ingredients, same manufacturing process, same factory, different testing regime, different paperwork...)

From Wikipedia

Even though the legal requirement in various nations would be different, the food safe symbol generally assures these:

That the container surface is free of any toxic contaminants which could be contacted from the manufacturing process.
That the material the container is made of shall not potentially become a source of toxic contamination through usage (degeneration). This is assured by estimating and regulating the 'migration limits' of the material. In EU regulation, the overall migration is limited to 10 mg of substances/dm² of the potential contact surface. The specific migration for various materials would be different for different temperature levels (of food as well as storage) and for different food items depending on variables such as pH of the food stuff. The toxicity considerations of a specific material may include the carcinogenity of the substance. The regulations governing these aspects may vary in different nations

Get some silicone tubing off vossy on here its great. Who said you need expensive cam lock fittings to brew any way

Just went off googling on water shortages... bear with me, this is going somewhere...

...and found these http://www.easywatering.co.uk/acatalog/ ... tings.html

Which means you could do Vossy's silicone tube + quick connects for nice easy dismantling of kit... :hmm:

 

[Darcey]

+1 silicone tubing from vossy! Great stuff.

If you are setting something up permanently then why not copper? Not cheap but you can always scrap it in one day?

I tend to find Jguest push fits a PITA anyway. I should really get the tool!!!

Same fittings are half the price at screwfix :thumb:

That's how I ended up finding them but they only seemed to do a pack of four bits for a hose...

...might have just been me being cr@p. Got a link?

:wha: I didnt say that :whistle:

 

[calumscott]

As you were... :lol:

 

[Darcey]

I think screwfix owe me some money for endorsing their products!

Unfortunately it needs to be compact and easy to dismantle after every brew.

The hoselock stuff was my first port of call but i don't think the seals will last at the temps of freshly boiled wort. I have found some lovely fittings from Parker but at the fat end of £20 for the coupling and £15 for the plug they are not cheap! :shock:

Vossy tube is my prefered choice at the mo for connecting the various vessels, I just need a way of swapping the pipes at each stage of the brew without spilling.

Camlocks are straight through I think so not suited. :cry:
