Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or
serious injury. Only use the O-ring that is designed for its specific flange adapter.

B. O-ring
C. PTFE based profile is square
D. Elastomer profile is round
Whenever the flange or adapters are removed, visually inspect the O-rings. Replace them if there are
any signs of damage, such as nicks or cuts. If the O-rings are replaced, re-torque the flange bolts and
alignment screws after installation to compensate for seating of the O-rings.
