stopcock taper?

Today i recieved a kontes 250ml equalized addition funnel, i managed to get the 24/40 stopper unstuck with water/glycerol, however the teflon stopcock is too small, water just flows right past in the closed position. On the joint it says its a $2 joint. I emailed the seller a bit ago on the subject. I was wondering if a $2 taper is a standard size for teflon or for glass stopcocks.
Thanks, Justin

Nevermind, i looked at the catalog and it originally comes with a ground glass stopcock
