@dharrington:
You didn't say what length of tank you have or what length carto you need. Cartotanks come in two lengths, 35mm (standard length) and 45mm (XL or DCT)
tanks. Likewise, cartomizers come in two different lengths to fit the two lengths of
tanks.
I'll take an educated guess that what you need is a
pre-punched XL length cartomizer with a flange.
Smoktech tank replacement cartos will almost always have a flange. I have a list of about 20 online vendors that sell pre-punched, single coil cartomizers in this link. Click the links in that blog article to go to the vendor websites to see if the cartos they sell have a flange.
