O-rings with flange adapters
WARNING
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.
A. Flange adapter
B. O-ring
C. PTFE-based profile (square)
D. Elastomer profile (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.

are required. For M20 threads, install conduit plugs to full thread
engagement or until mechanical resistance is met.
