Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
Easily assembled into one-piece piston because the 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 elements must be oiled with system
oil.
NOTES
For special applications that require high temperatures , piston
seal is manufactured in FKM and special mixture PTFE material.
