Finding replacement stopcocks for kontes dean stark apparatus
I recently purchased some used glassware and some of them arrived without a pfte turning valve stopcock (yes I checked if the joint is cloudy or not and they are clear so I know it needs a ptfe stopcock) I measured with calipers and for most of them it was pretty easy to find a replacement, but for this Kontes dean stark apparatus/trap I couldn't find anything. I'll add all the measurements below that I could accurately get
The wider hole is 14mm and the smaller one is 10.5mm and the length is 30mm
I checked ebay and other websites to see if there was a stopcock with similar measurements. The closest I could find is a 15.2/30mm ptfe stopcock which obviously isn't close.
The Kontes dean stark piece doesn't come up when I search for it on google. I only get things that are pretty close to it but not exactly the one I have.
