Function Resise shock loads, wear, comtamination, and will resist extrusion or chipping



1. Low friction, high efficiency.

2. Easy onto a solid piston without tools.

3. Unusually high wear resistance.

4. High resistance qgainest extrusion.

5. Perfect sealing performance.

6. Good temperature tolerance.

7. Double lips prevent dust pollution.


Direction For Use:

1. Clean the OK seal mating surfaces and shafts.

2. Ensure that the shaft is dry and free of grease or oil, especially in the absence of axial support.

3. Such a group of parts should have an axial gap. To avoid damage to the sealing lip, do not pull the seal on the sharp edge during installation.

4. These seals are typically incorporated into closed channels. Special installation tools are required where the entrance is restricted.
