The RP-30 is a single acting piston seal which consists of reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element.
- functions even with poor surfaces
- reinforced cotton fabric base prevents the seal from extrusion
- both rod and piston application
- good sealing at low pressures
Low to medium duty hydraulic cylinders, mobile hydraulics and presses.

The RP-30 is to be assembled into open grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
permissible sealing gap
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
