Hi all -
I am looking for very small rubber stoppers that can be used to plug the end of a 3/8 vinyl tube.
I have some little red stoppers that are used with THA nestmates, and they are perfect. Problem is, I don't have access to them right now (long story) so I'm looking for a replacement. I am able to find lots of stoppers around on the internet, and they are cheap, but I can't find a size that will work for this application!
Doest anyone have a reliable way to plug a tube? I want it to be water tight, i.e. like using it for a nestmate.
thank you!
