Examples of Piston seal installation Piston seal example

The piston seal is designed to ensure that pressurized fluid does not leak between the piston and bore as the system pressure pushes the piston down the cylinder bore (dynamic pressure sealing)... More Info



Seal Design Considerations:

  • Non-symmetrical Piston Seal Design
  • Lip vs. Squeeze Type Seals
  • Seal Lip Geometry

More Info on Materials


*Pressure values are guidelines that depend on seal material, seal configuration, seal housing design, fluid or medium, operating temperatures, pressures, surface speed, and working environment. For maximum seal life expectancy, do not operate your seal beyond 75% of its operating limits.


For pressures exceeding 8000psi Please consult our engineers at engineering@ahpseals.com or call 1-800-283-7140 for advice.
