Review on 🖤 Black Fluoroelastomer Sheet Gasket with Viton by Ronnie Segobiano

I have had to store small amounts of toluene and other solvents in small bottles but have had difficulty finding suitable bottles outside of very expensive lab equipment. My solution was to buy some inexpensive glass bottles with caps and replace the plastic spacers with discs cut from Viton sheet. The solvent doesn't come in contact with anything other than glass and viton and the containers work great. Buna-N swells significantly when in contact with toluene and some other solvents, while Viton does not.
