No. The shuttle itself has a seal at each end where it enters the pressure
chamber on either side. In between it is open to atmosphere. If you get fluid
leaking from the switch the PDWA needs new seals.

List,
Does the switch on the top of the PDWA valve (TR6 and 250 and others I guess)
have any type of seal between it (the plastic switch) and the brass PDWA
housing? No apparent seal from what I see in the TRF TR6 Parts Manual, although
the drawing of the switch would seem to show a seal of some type. No separate
listing for a seal is shown.
Thanks,
JVV
