Tapped connections for the purchaser’s use in the future for buffer gas applications.
Application Notes
Used on Arrangement 2 seals, where the potential for use of a buffer gas system in the future is desired, even though no buffer gas system is provided at the time.
All seal ports should be connected to piping or metallic plugs must be used if a seal is to be put into service.
Ensure vent port is oriented to the 12 o’clock position and the drain is oriented to the 6 o’clock position.
May be modified as needed into several other plans such as Plan 72, 75, and 76.
