What size rubber stopper fits a 24/40 joint?

evil_lurker,

Here's a photo of a page from an old Fisher catalog - a very handy book to have.

As you probably already know cork stoppers use a different numbering system.

I like to use rubber when it works, but many organic solvents make it swell or otherwise deteriorate. In those cases I use the cork stoppers. I can find some of each at my local hardware stores. They are of poorer quality, however, compared to those of the lab suppliers.
