Piston Cups are available in various shapes and compounds. The selection should be made on the basis of pressure, temperature and the type of air or fluid in which the cup must function.  Homogeneous or Neoprene cups are made to handle low pressure (under 150 lbs./sq. in). Recommended for applications against air and petroleum based fluids. Exceptionally long lasting with high abrasions resistance.  Buna-N and Cotton Duck Fabric (F-Series) piston cups are also available.

Buna-N and Cotton Duck Fabric are designed to handle moderate pressure cylinders up to 1500 PSI. Against air, water and petroleum base hydraulic fluids and lubricating oils. Neoprene piston cups (NP Series) are also available.
