HUNGER OBVD O-RING

    OBVD O-RING

    The OBVD ax/2ax reliably prevents the O-Rings from entering into the gap (gap extrusion) by means of their highly extrusion-resistant back rings.

    The OBVD 2ax version is suitable for pressurization on both sides, e. g. as a static seal between piston and rod.

    The NBR O-Ring, which is firmly fixed to the PUR back ring, compensates for design clearances and
    tube breathing.
