Material
Polyurethane (PU)
Premium polyurethane compound engineered for superior sealing performance in general hydraulic applications, standard colour blue.
PU seals — high abrasion resistance for hydraulic applications.
Applications
Where it's used
Rod seals, piston seals, wiper seals and general hydraulic sealing where superior wear life is required.

Key advantages of Polyurethane
- Exceptional abrasion and tear resistance — 5–10× better than most rubbers
- Very high tensile strength (up to 50 MPa) and load-bearing capacity
- Good resistance to mineral oils, greases, fuels and hydraulic fluids
- Temperature range from -30°C to +80°C (special grades to +110°C)
- Excellent extrusion resistance at high pressures — ideal for hydraulic piston and rod seals
FITCO supplies polyester- and polyether-based PU seals and O-rings for hydraulic cylinders, pneumatic systems, and high-pressure applications where conventional rubbers extrude or wear prematurely.
