A Viton O-ring, compatible with all
standard ll uids, and a Te on back-
up ring provide a seal between the
diaphragm capsule and the top
housing.
A thin Te on PTFE gasket between
the diaphragm and bottom housing
assures a leak-tight corrosion resis-
tant seal even at high pressure.
Top housing and pressure instru-
ment are removable.
Continuous-duty design will prevent
loss of process uid if pressure
instrument is removed or fails.
The comprehensive line of Ashcroft
diaphragm seals will meet a wide
variety of application or installation
requirements. Over 30,000 variations
are possible with the types, connections
and materials available.
The top housing and diaphragm
capsule are interchangeable with
all Ashcroft bottom housings.
A ll/bleed connection is standard,
which permits lling the seal and
instrument simultaneously after
evacuation and allows the ll to ow
into the completed unit.
