I need to know what type of tubing to buy for cooling the water-cooled spindle I have ordered. I contacted Probotix and they told I need 1/4"ID 5/16"OD with 1/32" wall thickness. What I need is recommendations for what material type I should be looking for. Thanks in advance for any replies.

I used silicone tubing - Silicone tubing - OD 7mm ID 5mm. It has worked fine for the last year or so.

Let me get it straight. You asked what size of tubing you need, but did not ask what type of tubing was recommended? I would get back to the company on that.

Theo it's more fun to ask that question here. Besides this is (his or hers) first post.

By the way Rider welcome to the forum.

I don't know how many feet of tubing you need however here is what I used on my 2.2kW water cooled spindle.

Ditto the welcome, Rider! I didn't notice it was your first visit when I commented.

You can buy Custom Heat Shrink Tubing. (advertising link removed by moderator)
Heat shrink tubing is a durable thermoplastic tubing that is designed to shrink in size when placed around wires or cables and then heated. As an alternative solution to taping or molding wires togethers, the heat shrink tubing works as an organizer or labeler for clusters of wires. It also acts as an insulator and added layer of protection from external elements.

I'm going to rekindle this thread. I have a 1.5KW water cooled spindle and I use 1/4" ID x 3/8" OD vinyl hose for coolant flow. Both the hot and cold hose route along my wires in both X and Y axis inside my drag chain. The smallest radius bend is ~4-5". I am going to place a tank underneath my router table and have already purchased a submersible pump. However, I noticed that just blowing into each of the tubes requires a lot of pressure. What type of pump is preferred? Thanks guys!

Try an aquarium store or supply on internet. I think you can get all power levels in that kind of pump, and they are designed for very long life. Some are submersible but not all. You can also get inline filters, but you might want to find some chemical that isn't harmful to the pump, tubing or spindles cooling system, but will suppress algae. For long runs, that fluid is going to gradually warm up.

While doing my research, which I admit is hindsight, I discovered that I need a high-pressure, low-volume submersible pump. The pump I chose initially which was recommended by another DIY CNC Router, was basically a pond pump which has an impressive 9.1 gallons per minute (34.5 L/min) flow rate, but has only a lift of 5 ft (1.5m). The link to this pump is below: https://www.amazon.com/gp/product/B017R708QO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Now that I know the requirements of the pump I need, I discovered a 12V pump that had a flow rate of 3.7 gal/min (14L/min), but a lift of 16ft (5m)! I feel really safe that my submersible is a 12V device and not a lethal 115VAC. Here is a link to it:

I should have it in my hot hands by Wednesday.
