KASTAS - ROD SEALS

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
• Construction machinery
• Cranes
• Injection moulding machines
• Mobile machinery
• Industrial cylindersMaterial Code Pressure

K31 heavy duty rod seal is designed for working at hydraulic rod applicaitions consisting of special geometry polyurethane seal, elastomer ring that works as an energizer at low pressures and thermoplastic backup ring for superior extrusion resistance.Advantages• Superior static and dynamic sealing effect
• Design providing good sealing performance at svariable pressure levels.
• Improved sealing gap thanks to the back-up ring
• Safely operating with the elastomer o-ring in long duration locking systems
• High wear resistance and compressive strengthArea of Application• Mining industry
• Iron and steel industry
• Scrap metal presses
• Mobile machinery
• Marine hydraulicsMaterial Code Pressure
