OMG!!!! WARNING! IMPORTANT! This guy is tightening ***INCORRECTLY***. Do NOT rotate the male component (screen left) as he shows. You should only rotate the nut that is over the CSST tubing. Incorrectly rotating the male component will gouge and ruin the inner mating surface, ruining the fitting and causing a dangerous gas leak. Everything else is correct. But DO NOT rotate the male component as show here. Please consult the gastite instructions.
