NOTE
Table 3-10 refers to the chemical resistance of the solid material in liquids. However, the resistance
against the corresponding vapors is significantly better. Tabled values may vary by changing temper-
ature and pressure.
The PETP vacuum cover is equipped with EPDM O-rings. A set of 12 FKM O-rings is enclosed.
Alternatively, there are highly resistant FFKM O-rings available. The PEEK vacuum cover is equipped
with FFKM O-rings by default.
