HUNGER STI-STA O-RING

    STI-STA O-RING

    HUNGER support rings are mostly used with static O-Ring seals. They reliably prevent gap extrusion of O-Rings under pressure load.
    Due to the geometry of the support rings (profile L and C), deformation of the O-Ring produces a radial load component which ensures that any gap is totally bridged. The profile and thickness of the back-up ring
    ensures that even at extreme pressures the O-Ring is prevented from extruding.
