Yes, like a drip tip would. The intention was to prevent condensation and or juice from accumulating outside the tank. I've never seen any improvement with the newer top screw in that regard.
Depth is 2mm. OD measures 8.2mm. Measured with a rule. Someone needs to mic this to check my accuracy though.
Ok so if I go 8.5mm and 3mm depth we should be good for either style.
