Although not yet listed on the website,
IBTanked will soon be offering a 15mm outer diameter cartotank made of pyrex and stainless steel caps.
OCD was kind enough to send me some prototypes to try out last week. These are the same high quality glass tanks with stainless steel end caps as the other tanks offered at IBTanked. You can view an
image of the prototypes here on IBTanked's supplier forum:

Here's what is listed on the website
FAQ page:
"Q: What type of cartomizer fits the tanks?
A:
Any XL (45mm) 510 Cartomizer should fit our XL tanks.
Any Standard (35mm) 510 Cartomizer should fit our Standard tanks.
Mini (19.8mm) Cartomizers, aka HalfLing, will fit our HalfLing Tanks.
We have had HalfLing Cartomizers made especially for us with 2 holes and a Flange like our other popular SmokTech Cartomizers. Note that the holes have been lowered 3mm and may not work in tanks with thicker caps than IBTanks. Boge cartomizers are often listed without the thread length so you may see 40mm and 30mm for XL and Standard on those.
Q: Are there any other types of caps.
A: We have Both Stainless Steel and Anodized Aluminum. We are adding more choices as we can.
Q: What length do the tubes come in?
A: The tubes are 0.60", 1.21" and 1.57" for the HalfLing, Standard and XL respectively. They finish out with the caps and washer nicely on both Standard and XL Cartomizers almost flush on the ends.
Q: What is the ID and OD of the tubes.
A:
15mm tubes are 15mm OD and 12.6mm ID
19mm tubes are 19mm OD and 14mm ID
22mm tubes are 22mm OD and 17mm ID
25mm tubes are 25.4mm OD and 20.4mm ID"
