V-packings are 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 im- proved the characteristics of conventional V-packings.Standard versions contain pressure and support rings of POM or PA and V-packings of fibre reinforced NBR. The DMD1/DMD2 series has additional NBR V-packings.The total width is determined by the number of V-pack- ings used (up to five). Non-adjustable installation grooves can be compensated by distance rings, if ne- cessary.The width of the support and the pressure ring can be adjusted to suit customer requirements. The stated di- mensions m and k are recommended sizes only.
