If you're talking about the DCTank, many of us have been chasing this tubing. So far, no one has found it. Most
tanks use 5/8" id x 3/4" od tubing, and it is thicker. I am starting to think that this DCTank has a proprietary sized tubing. Personally, I have been looking for polypropylene tubing instead of polycarbonate. This is the same material that syringes are made from, and it seems to be just about indestructible as far as cracking problems from juices.
If you're talking about the slim
tank, I haven't gotten one of those yet because I prefer the larger capacity. I would guess that it's the same story.
Has anyone else had success finding tubing that fit the DC slim tank?
