Pumping piston cartridge - WP air

AlcoTech pumping piston with double seal for WP air cartridges: the first seal is made of PTFE with an energized profile to withstand high pressures during dynamic operation, the second is made of nitrile compound to ensure a hermetic seal between the chambers. The combination of the two seals allows for consistent performance over time, controlling friction levels even in case of poor lubrication.
