TPM Combined Piston Seal | Zero-Leakage High-Pressure Performance * Extended Service Life * Precision Engineered Sealing Solution

Engineered for demanding hydraulic/pneumatic systems to minimize downtime and maximize equipment reliability

TPM combined piston seal, a hydraulic piston seal made of NBR and PTFE materials, model TPM-393295/393314 TPM combined piston seal, a hydraulic piston seal made of NBR and PTFE materials, model TPM-393295/393314
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
  1. 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.
  2. 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.
  3. Engineering validated performance
    • 10 million cycle durability test (simulating heavy machinery conditions)
    • Compatible with biodegradable hydraulic oil (environmental compliance)
