Hydraulic Cylinder Seals - High Pressure Hydraulic Seal

Hydraulic Seals

Hydraulic-SealsPerformance Sealing Inc (PSI) designs and manufactures a full line of hydraulic sealing solutions. A hydraulic sealing product is actually a family of products used to seal reciprocating, oscillating or slow rotational movements caused by hydraulic equipment. A hydraulic seal, at the end of the day, must prevent leakage of fluids from cylinders. Hydraulic seals can come in many sizes and forms based on the duties they must perform. Hydraulic seals are usually surrounding rods, rams, glands or the piston and used a different design or combination of interlocking lips and components.

PSI Seal combines material technology and seal design to optimize your hydraulic seal's performance. PSI Seal material technology uses high performance engineered polymers made from:

  • PTFE
  • Duron® PTFE based compounds
  • PEEK
  • Polyimides
  • PPS
  • other polymer materials specified for your application.

PSI Seal's selection of the right spring energizer design and sealing profile is also critical to optimal sealing system performance. Our design process consist of working closely with you to understand the sealing requirements and then applying our design expertise and joint test program to develop the right sealing solution that improves your products sealing performance.
