Size tube needed to go over brake bleeders?

[Toro]

I was going to pick up some of that clear tubing from Lowes to use with brake bleeding. Just wondering if anyone happens know the correct ID to use that will fit properly. Looks like Lowes has a few sizes, and didn't want to buy several just to try if someone remembered. It's factory rear drums, and front discs on a 72 Blazer.

Also, would anyone recommend a specific one of those prop valve bleeder tools that screw in at the dash light plug? Last time I had someone hold that button in on the front of the prop valve and it was a pain. Thanks!
