Materials
The Parker material P5008 is a polyurethane-based elastomer, hardness 93 Shore A.
Compared to other polyurethanes, it has very good heat resistance, low residual compression and improved hydrolysis resistance.
Installation
Mounted in a closed groove.
Seals are available for grooves corresponding to ISO 5597/1.
Advantages
-Especially good wear resistance
-Highly resistant to pressure spikes and impact loads
-High gap penetration resistance
-Low residual compression
-Suitable for tough conditions
-Adequate lubrication due to oil between the sealing lips
-Reliable operation even in unpressurised conditions
-Air intrusion into the cylinder from the outside is largely prevented
-Easy to install
