hey,
the circumference of the 'washer plate' that the main o-ring sits on ;
is SMALLER on the T3S coil
it is BIGGER on protank coils and won't fit INTO T3S tanks
- - - -
so I buy T3S coils, and they fit in all my kanger bcc's
- Kanger T3s/Mini T3s/MT3s

Great observation puff. The flange part of the assembly is different in diameter by about 1mm. However, the 3TS head will tend to leak past the flange a bit more into the 510 threading. There's less of the flange surface to mate with the base. So it'll get you out of trouble in a pinch but I wouldn't recommend it.

Good luck.
