I need to buy some more of the water cooling tubing.

What is it and where can I get it (UK)

Thanks

It is usually 3/8" silicon tubing - but you can use anything that is similar - I am no help on sourcing in the UK

Hi Phil

Typically silicone tubing is used (mine is 3/8” or 10mm) inside diameter, yours may be different.

Purchasing in the UK you could try medical or lab supply house, online try the usual places like eBay, AliExpress, Amazon, etc.

On my machine I only used the silicon tubing from the laser tube to the back of the machine where I connected it to brass bulkhead fittings with a hose barb on each end and a way to secure the fitting to the metal cabinet. From there I went with hose that was easy to get from my local hardware store to my water reservoir. The bulkhead fittings I purchased on eBay and I used a plastic zip tie around the tube and fitting to prevent leaks.

The soft silicon tubing should be used on the glass tube because it is unlikely to create any stress into the glass putting it on or taking it off.

Good luck.

Silicone or poly. Silicone is definitely more flexible, but it is also much more likely to kink in sharp turns.

Thanks all, I have ordered some silicone tubing, hopefully it fits
