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. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring that is designed for its specific flange adapter, as shown below.

Whenever the flanges 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 PTFE o-ring.
