HUNGER ZSDA PISTON SEAL

    ZSDA PISTON SEAL

    The ZSDA seal for cylinders with radial drillings is a piston seal which can dynamically operate over drillings in the cylinder bore up to 3 mm diameter. It can also be used as a high pressure seal on cylinders with-out radial drillings up to 2000 bar.

    The ZSDA seal consists of 5 parts. Two L-shaped metallic support rings and an intermediate metallic thrust ring support a slide ring of PTFE compound withM narrow sealing lips on its outer diameter. An O-Ring acts as energiser to provide a sealing function even at zero pressure.
