Fig. 7.40: Replacing the conical adapter O-rings
The O-ring of the conical adapters may become either chemically or physically damaged under harsh
conditions or upon intensive regular use respectively.
The vacuum cover is equipped with EPDM O-rings. A set of 12 FKM O-rings is enclosed. A list of
recommended applications and restrictions depending on the material is given in Table 3-8.
Alternatively, for very harsh conditions FFKM O-rings are availble (see also chapter 10.2), which are
provided on the PEEK vacuum cover.
In order to remove the O-rings push with one hand horizontally and with the other vertically to the top.
