What Are Hydraulic Seals?

Hydraulic seals are precision-engineered components that seal reciprocating, oscillating, or slow rotational movements in hydraulic systems. These critical components surround rods, rams, glands, or pistons, using specialized designs with interlocking lips and components to maintain system integrity. At the end of the day, a hydraulic seal must prevent fluid leakage from cylinders while maintaining optimal performance under challenging conditions.

As a trusted hydraulic seal supplier, PSI combines advanced material technology with innovative seal design to deliver superior performance in high-pressure environments. Our expertise spans decades of developing solutions for the most demanding sealing applications across multiple industries.

Advanced Materials for High Performance

Our high pressure hydraulic seals utilize state-of-the-art engineered polymers that deliver exceptional performance in extreme conditions:

PTFE - Superior chemical resistance and low friction properties
Duron® PTFE-based compounds - Enhanced durability and wear resistance
PEEK - Extreme temperature performance up to 500°F
Polyimides - Outstanding mechanical properties at high temperatures
PPS - Excellent chemical resistance with dimensional stability
Custom polymer materials - Engineered specifically for your application

The selection of the right material is critical to hydraulic seal performance. Our engineering team analyzes your operating conditions, chemical exposure, temperature ranges, and pressure requirements to recommend the optimal material solution that maximizes seal life and system reliability.
