well i just bought 6- #9 stoppers for $11.00 they are 15-16 mm long x 9.3 at the ground joint top end and i miked my thermometer port of 10/30 and it was at about 9.7mm x 30 so i am hoping it will fit. i found a really good bargain at science lab .com but the guy there got really raunchy with me so i dont want to go back begging.i only told the guy that if my order wasnt able to be shipped not to charge me for shipping because one seller actually wanted me to pay a cancellation fee for the tracking notice that was automatically sent to my e-mail.

does any one know what number pertains to 10/30 penny head stopper? some sellers have a given number for stoppers,for example# 24 would be 24/40 and #19 is 19/22 etc.. i have seen #9 and is close to 10/30 but have not seen any #10. thank you.


Stoppers come in two flavours the Standard Taper flavours where they will be say 24/40 and the stopper sizes which only indicate the maximium diameter number Ie a #24. the stopper joints are shorter and will jam in a standard taper.

There are a couple of threads which explain the diffrence in detail.
