ASTON KDF PISTON SEAL

    KDF PISTON SEAL
    – A seal that ensures good reaction to load peaks and low friction in the low pressure range. The lips asymmetrical are designed to differentiate behaviors on static surfaces and dynamic: the static one is more flexible sensitive to pressure changes e guarantees a large contact surface; the dynamic one is shorter and stiffer for concentrate the load against the surface dynamic.
    – An angle guide ring that supports i radial loads and drives the piston into the cylinder
