PolySlide® composite cylinders offer drop-in replacement in these and other applications:


  • Pneumatic actuators for valves
  • Respirators for medical applications
  • Hydraulic actuators for aircraft
  • Pressure pumps for spray applications
  • Dump mechanisms for railroad cars
  • Waste water treatment flow control mechanisms
  • Pneumatic/fluid shock absorption or energy diversion

PolySlide® works as a replacement for aluminum, steel and brass cylinder tubing in pneumatic and hydraulic systems.

Application Considerations

  • Conventional end seals and closures can be used. Steps and shoulders may be machined if required. Bearing stress must be no greater than 25,000 PSI.
  • Non-metallic seals on the piston must be used.
  • Compression of approximately 0.006 inches per each inch of cylinder length should be used when and where the maximum pressure is required.
