Review on Canton Racing 45 000 Expansion Tank by Mike Bucher

I am using this in an application where I need to do remote ventilation. So I have to remove the built in bleed screw. The first tank had a completely transverse thread. The armor threads are destroyed. The second tank also had problems. Although the bleed screw appears to be screwed in straight, it was overtightened and the threads were stripped. Both sets of bottom threads were fine on both tanks.
