Apprentice question

Field check

Standard work. Do it right, keep moving.

Can over-tightening round companion rings cause leaks?

Yes. Over-torque can warp the ring and damage the gasket. Reset the joint with a fresh gasket and even tightening by manufacturer direction.

['Big round companion rings need even compression. A breaker bar can stretch holes, warp the angle ring, and cut the gasket instead of sealing it.', 'Disassemble the bad joint, replace damaged gasket, dress/replace warped rings as needed, then tighten evenly in a cross-pattern to the approved torque or manufacturer instruction.']
