The PEI Tank Kit for the Prime is a tank version of compromise. A viewing gap on the bottom side of the tank provides certainty about the tank contents without losing the steel tank optics. Matching the viewing gap, the kit includes a tip insert for the Drip Tip of the Kayfun Prime made of the same, robust plastic material (polyetherimide), also known as "Ultem".
The max. fill volume is 3.3ml with this tank.
