Water-cooled spindle tubing

[d4cnc]

Is there a recommended tubing to use?
I need to extend the tubing already supplied with the spindle and I currently have 2 types of 10mm tubing that I could use..
I have some braided PVC hose.. like this stuff.. http://www.amazon.co.uk/clear-braided-grade-water-reinforced/dp/B00I9B0I1S (ID10mm OD about 14mm)
It says food grade so presumably meets the standard needed for my needs? It doesn't say anything about plasticizing.. not sure if that could be a problem...


Or I have some more water cooling PC type tubing.. 10mm/16mm https://www.overclockers.co.uk/mayhems-ultra-clear-watercooling-tubing-38-58-10-16mm-wc-114-mh.html
This doesn't say anything about food safe.. but it does state that it uses polymer additives that doesn't leach plasticizers..


Would either of these tubes be ok to use?


Is there a preference? (I'd prefer to use the first type as it's in my hands currently whereas I'd have to wait a few days for the second...)

Any assistance greatly appreciated!

Any tube will do is my understanding.

Any pipe will do but are you sure the connectors are 10mm.? This seems little on large side for these spindles.

Personaly I remove these and fit Air line pushlock connectors and use 6mm air pipe.

Great.. thanks guys.. I've put in the tube I have here..


Yes the spindle tubing on there at the moment is smaller in diameter, but as it's not long enough and I want to bring it to a computer radiator anyway, I thought I'd couple it on to a larger diameter tube.

Hi Guys,

This thread reminded me that when I tried to fit the water pipe I could not get the collar to engage with the thread to clamp down the pipe. I put the problem to one side, to sort it out when I installed the spindle. Deans remark about changing the connectors to air hose ones made me think I might be able to use the push fit connectors as on the right of the picture. but the thread to the spindle body is not 1/8 NPT as it has an outside diameter of 7.5mm. Anybody got any suggestions as to what it might be ?

Cheers,

Rob

If you can measure the TPI (threads per inch) of the thread it will make identification much easier - google a few thread charts such as :

Can tell you exactly what it is. . . . . M8 x 1mm Fine thread.

Spot on mate, I just went to the workshop and checked it with a M8 x 1.00 die. Well at least I can make some adapters, if I can't buy them.

Cheers,

If anyone is looking for the fitting Jazz is recommending here's a link to some on ebay:

High Pressure Metal Push-in Fittings for Air or Central Lubrication Systems Tube

http://m.ebay.co.uk/itm/271182576634

Look a bit posh and a bit pricey at 3.50 a pop, not sure if Dean has a better price?

Cool couldn't see it anywhere, I just put a message out to a few of the aliexpress boys to see if I can get a price, closest I can find listed is PC6-M8 corse.

I bought some adapters, M8 male to 1/8BSP female from Context Pneumatic in Bolton, pricey at £4.98 each, but their push in fittings are cheap.

Cheers Rob,

Just got word back on these:

10pcs/lot 6mm Tube M8 Thread Pneumatic Fitting Quick Joint Connector PC6-M8

http://s.aliexpress.com/IbA3QVjq

Says they are M8x1, if you go via the mobile app you get 16% off, works out about £5 for 10 or around 40p each, not quite the same as the others.

Dean how comes you change them for push fit type anyway, are the standard clamp type not very good that come with them?

Lee,

See post #5. My reason for wanting to change the fittings was that I couldn't get the original fittings to clamp down over the pipe (8mm OD 6mm ID). As I have many metres of this pipe, I didn't want to buy any more of a different size. I would have liked M8 male to 8mm push in, but couldn't find it directly. I have the brass, taps and dies to make an adapter, but couldn't be arsed to, when they were available to buy.

Ahh I see, in the end this was the best price I could find for 6mm od x M8, there listed as 1/8 but if you message the seller first he'll send you the M8x1, I know you don't need them but others may and this is mostly for Jazz if he's interested in buying them cheaper.

Just don't like them also means can use smaller Dia tube.

I think that polyurethane tube is a nice touch, now that they are cheap on ebay. And if transparent and cooling liquid pink red, then even better for the "Frankenstein" effect

Hummm, black frame, green plates, red veins...when are you painting your machine Boyan?

You go first - I follow the colour scheme :-)

Pink antifreeze, add red food dye, nice soft clear silicone tubing and pulse the flow at about 80 b.p.m. - you could really make your machine come alive !
