Single acting lip seal, paired with pre tightened O-ring, provides better pressure holding effect. The outer secondary lip at the root enhances its static sealing performance with the groove, and the inner secondary lip at the root enhances its long stroke sealing performance. With the cooperation of the retaining ring, it can apply higher pressure and allow for larger extrusion clearance

• Application location: Hydraulic cylinder piston rod or plunger
• Advantages: Easy to install, good anti extrusion performance, high pressure bearing capacity
• Material: polyurethane/rubber/plastic material
