KPR PISTON SEAL
A dynamic seal that ensures a high level holding capacity. Two small and compact sealing lips ensure perfect fluid control and concentrate the load against the dynamic surface.
Features
• High sealing capacity even at low pressure
• Excellent wear resistance
• Small footprint
• Long service life
• Simple execution of the seat
• Economic solution
• High resistance to extrusion
• Good temperature resistance
• Easy to install on monobloc piston
