Forgot to mention, don’t buy pumps from those websites that sell cylinders because cylinders are their specialty. They usually just resell pumps from other manufacturers so they’re much more expensive. For example, if you lived in the US, you could buy a pump for $20-25 in Harbor Freight. That same pump goes for $50+ on websites dedicated to pumping.
In other words, buy a pump in local hardware or car parts shop or order it from Amazon or similar website. I recommend Mityvac MV8000.

From what I can tell, no. If you look at the pictures, their cylinders have very thick walls. The cylinder that I’m using is low budget and with much thinner walls, but it doesn’t require sleeve.
