High-Quality ZP Hydraulic Seal
Multi-Material Seal with PTFE, Fabric-Reinforced Fluororubber & Nitrile Rubber
The ZP Hydraulic Seal is a high-performance sealing component engineered for reliable use in hydraulic systems. Its robust multi-material composite structure is designed to deliver exceptional sealing efficiency and long-term durability, addressing the demands of industrial hydraulic applications.
At its core, the seal consists of two PTFE backup rings—known for their low friction and chemical resistance—paired with a central fabric-reinforced fluororubber layer that enhances structural strength while maintaining flexibility. Completing the design is an inner nitrile rubber elastic ring, which boosts sealing tightness and adapts to dynamic pressure changes in hydraulic circuits.
This combination of materials ensures the ZP Hydraulic Seal resists wear, oil, and harsh operating conditions, making it suitable for use in machinery, construction equipment, and industrial hydraulic units where consistent, leak-free performance is critical. It balances resilience and precision to meet the needs of high-pressure hydraulic systems, reducing maintenance frequency and extending equipment service life.

More Choices
1. Product Advantages
- Superior Durability: The multi-material structure (PTFE backup rings, fabric-reinforced fluororubber, nitrile rubber inner ring) resists wear, oil, and chemical corrosion, extending service life in harsh conditions.
- Reliable Sealing Performance: PTFE’s low friction reduces leakage risks, while fluororubber’s elasticity and nitrile rubber’s tight fit adapt to dynamic hydraulic pressure changes.
- Wide Compatibility: Engineered to work with most hydraulic fluids, making it suitable for diverse industrial operating environments.
2. Working Principle
The ZP Hydraulic Seal operates through a synergistic design of its components. When installed in hydraulic systems, the two PTFE backup rings prevent extrusion of the central fabric-reinforced fluororubber under high pressure. The fluororubber layer forms a primary seal against fluid leakage, while the inner nitrile rubber elastic ring compensates for minor surface irregularities of mating parts—ensuring consistent, leak-free performance even during system pressure fluctuations.
3. Product Details
- Material Composition: 2x PTFE backup rings (corrosion-resistant, low friction); 1x fabric-reinforced fluororubber layer (high strength, flexible); 1x nitrile rubber inner ring (excellent elasticity, oil-resistant).
- Design Feature: Compact composite structure, easy to install in standard hydraulic seals grooves.
- Quality Assurance: Manufactured by Forever Seals with strict material testing and performance validation.
4. Application Range
Ideal for use in:
- Industrial hydraulic machinery (injection molding machines, presses)
- Construction equipment (excavators, loaders)
- Agricultural machinery (tractors, harvesters)
- Heavy-duty hydraulic systems requiring high-pressure resistance (up to 35 MPa).
