HUNGER DMD V-RING

    DMD V-RING

    HUNGER V-packings are an extension to the DFE product range for sealing piston rods and pistons. Due to their profile, V-packings can be used for both outside and inside sealing.

    The use of plastics with good stability of shape has improved the characteristics of conventional V-packings.

    Standard versions contain pressure and support rings of POM or PA and V-packings made of NBR fabric. Complete V-packing sets with pressure and support rings made of NBR fabric or combinations of rubber packings and fabric packings are available.

    The total width is determined by the number of Vpackings used (up to five). Non-adjustable installation grooves can be compensated, if necessary.

    Depending on the application, the width of the installation groove can be determined from the following pages.
