Reaction vessels for vacuum and pressure

Accessories
Gaskets
Gaskets for pressure and vacuum use at temperatures
up to 250 °C are made from PTFE and are 1 mm
thick except lid gaskets which are 2 mm thick.
The final digit of the catalogue numbers for PTFE
gaskets is ‘1’.
Gylon beige is a modified PTFE gasket. The material
has similar properties to PTFE, but is more resilient
and does not creep as readily as PTFE. The upper
temperature limit is slightly higher at 260 °C.
The final digit of the catalogue numbers for Gylon
gaskets is ‘5’.
For maximum temperature resistance Klingersil
gaskets are used for both pressure and vacuum
applications. Klingersil gaskets are 2 mm thick.
The final digit of the catalogue numbers for Klingersil
gaskets is ‘4’.
Klingerite gaskets contain asbestos and are no
longer available.
Certain gaskets are made from aluminium. They are
1.5 mm thick.
The final digit of the catalogue numbers for aluminium
gaskets is ‘3’.
