K18 is a five piece double acting compact seal
which consists of one elastomeric nitrile rubber sealing element , two
polyester elastomer back-up rings on both sides to prevent extrusion into
the sealing gap and two special profiled guide rings produced from
thermoplastic to absorb transverse forces.

INSTALLATION
Easily assembled into one-piece piston because the back-up rings and
guide rings are been produced in split forms. It is very important that
the assembly tools must be of soft material and have no sharp edges.
Before installation the sealing element must be oiled with system oil.
|
|
NOTES
For special applications that require high temperatures , piston seal is
manufactured in FKM and PTFE material.
