Consider Housing Rotation - Emerson rosemount 3051S series Quick Start Manual

Quick Start Guide
1.6 O-rings with flange adaptors
Failure to install proper flange adaptor O-rings may cause process leaks, which can result in death or
serious injury. The two flange adaptors are distinguished by unique O-ring grooves. Only use the
O-ring designed for its specific flange adaptor, as shown below:
A. Flange adaptor
B. O-ring
C. PTFE (profile is square)
D. Elastomer (profile is round)
Whenever the flanges or adaptors 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-rings.
