Leaking Turbo V Band Flanges

This is a perfect reason why we got away with the V band flanges. They are perfectly machined, then when you weld on them, they warp causing a major leak. The copper colored stuff on the flanges is the copper anti sieze to help rotate the flanges, otherwise the rust on them prevents me from being able to turn them. PLEASE SEE OUR VIDEO ON OUR MARMAN FLANGES WE MAKE. THEY SEAL 100%!
