O-rings with Flange Adapters
WARNING
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 you replace the o-rings, re-torque
the flange bolts and alignment screws after installation to compensate for seating of the
PTFE o-ring.
Bolt Material Head Markings Initial Torque Final Torque
Carbon Steel (CS) 300 in.-lbs. 650 in.-lbs.
Stainless Steel (SST) 150 in.-lbs. 300 in.-lbs.
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.
