Hydraulic and Pneumatic Seals...since 1975
The EXCLUDER 2 wipers are made of a PTFE element and an O-Ring having a sealing effect in the static part and, at the same time has an energizing effect on wiper in the absence of pressure.
The EXCLUDER 2 also has a scraping effect on the outside of the Cylinder and maintains a residual oil film on the internal part of the rod. Used with proper sealing, allows the hydrodynamic return in the cylinder.
PRODUCT ADVANTAGES
APPLICATION:
Mobile hydraulics , aluminum injection machines and industrial equipment.
INSTALLATION:
We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). 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 When EXCLUDER 2 wiper is being used with double lip sealing element we recommend a pressure relieving bore between the seal and wiper. For special applications that require high temperatures or resistance to chemicals , piston seal is being manufactured with special mixture PTFE and FPM material.
