K33 is a single acting rod seal with an extra lip designed for a wide range of hydraulic applications. K33 lip design offers an optimum oil film while the secondary lip provides additional wiping performance and system safety.Advantages• Secondary sealing lip provides extra protection against the
ingress of dirt particles.
• Very good sealing thanks to the cut processed lip structure
• High wear resistance
• Easy installation into closed grooves
• Wide range of standard products
• Simple groove designArea of Application• Presses
