RGY Hydraulic Seal– Piston & rod packings

The grooves of RGY piston packings and RNY rod packings are compatible with those for the SKY-packings. RGY-packings are designed to withstand back pressure and provide longer service time by adopting an improved wear resistant material.

RNY rod packings are designed exclusively for sealing rods. RNY rod packings made of a highly elastic compound achieve good sealing performance against eccentric movements.
