Exactly what I needed

I chose this tank over others because it didn't have any pre welded mounting brackets on it, this allowed me to fab my own brackets and install how and where I needed to place it in literally minutes!

Most Liked Negative Review

3.0

Did what I needed

Tank was great and matched what was advertised. The bottom fitting was only hand tight and sealed with pipe dope. I changed that before installing but I think it would have leaked. Would buy again.

This expansion tank exceeds my expectations, heavy wall, precise construction, clean machining, well thought out design. The finish is not polished, but very nice. I'm confident this will work well on my Lotus project
