Our rubber stopper, similar to a single-hole rubber stopper, fits into a 1" opening. Tighten the plastic nut and bolt that goes through it, and the stopper expands to seal the hole. The top of the bolt has a 5/16" hose-barb fitting for 5/16" ID tubing. The bottom has a 5/16" bore. Handy in the lab, but worth the price for the components alone.
