Product Overview
The TPM Combined Piston Seal represents a next-generation integrated sealing system optimized for high-pressure, high-speed piston applications. Featuring an innovative dual-material composite structure (e.g., PTFE + elastomer) and unified guide ring/sealing lip design, it delivers:
- Zero-leakage performance (static/dynamic sealing)
- Ultra-low friction coefficient (reduces energy consumption)
- Extrusion & wear resistance (handles pressures >400 Bar)
- Broad temperature compatibility (-30°C to +110°C)
Technical advantages
- Intelligent structural design
- Three-function architecture: The guide ring, main sealing lip, and elastic compensator work together to eliminate gap leakage.
- Self-activating pressure groove: Dynamic pressure activates the sealing lip--the sealing force increases with pressure.
- Advanced materials science
- Friction optimization layer: PTFE material reduces starting friction by up to 80%.
- High-strength backing: NBR, FKM, or polyurethane elastomers resist burst impact.
- Engineering validated performance
- 10 million cycle durability test (simulating heavy machinery conditions)
- Compatible with biodegradable hydraulic oil (environmental compliance)
