Universal pump sleeve Miscellaneous discontinued

I can't think of any sleeve I've used that is better than this. It works excellently for wet pumping. Silicone is easy to clean and maintain.

For when you need a replacement for that used up and worn out pump sleeve. It is also nice to have an extra around in case that situation comes up that your sleeve isn't working.

Pure silicone, stretches easily but maintains vacuum seal, clear.
