thank you

See my comment above. It says right on the head, LS15 and LS24 tubing.
You can also look that head model up on the cole parmer website where it also says, LS15 and LS24 tubing. I am not aware of aftermarket LS15 or LS24 tubing as I mentioned in a previous post. That is not the ideal head for calcium reactors. Heads that support LS17 tubing such as the 7518-00 or 7518-10 are best suited due to tubing being readily available at reasonable prices.

Anyhow, here is the head on the Cole Parmer website.

Here is another good deal on LS24 tubing.
