Gaskets

 WARNING

When installing remote seal systems which employ a gasket or a gasket and flushing
connection ring, make sure the gasket is aligned properly on the gasket sealing surface.
The user is responsible to ensure the gasket used does not exceed the temperature limits
of the process. Failure to properly install the gasket may cause process leaks, which can
result in death or serious injury.
In addition, make sure the gasket does not press down upon the diaphragm face. Anything
pressing on the diaphragm will be read by the transmitter as pressure. A misaligned gasket
may cause a false reading.

The intermediate gasket between the seal and lower housing is supplied when the lower
housing or flushing connection is provided. The default gaskets are listed in 

Table 3-1

based on seal type. The process gasket must be supplied by the end user. Tantalum
diaphragms are not supplied with default gasket, so a gasket option must be selected
when applicable.

If a lower housing is supplied, then the following gaskets are the default gaskets for each
seal unless another gasket option is selected.
