Hydraulic Seals

Hydraulic Seals created by Performance Sealing Inc. Performance Sealing Inc (PSI) designs and manufactures a full line of high-pressure hydraulic seal 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 fluid leakage from cylinders. Hydraulic seals can come in many sizes and forms based on the duties they must perform. A high-pressure hydraulic seal usually surrounds rods, rams, glands, or the piston and uses a different design or combination of interlocking lips and components.

Hydraulic Sealing Design

PSI Seal combines material technology and seal design to optimize your hydraulic seal's performance. PSI Hydraulic 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 consists 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 product's sealing performance.
