Can over-tightening round companion rings cause leaks

3rd YearRound, Spiral & Flat Oval DuctStandard Correction

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

Plain-English answer

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.

Ask Foreman

The companion ring at [location] has stretched bolt holes and a torn gasket from over-tightening. I pulled the joint back. Do you want fresh gasket and even torque per manufacturer direction?
