Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fluid/Gas Sealing: Designed to prevent leakage of fluids and gases in high-pressure hydraulic systems and mechanical equipment.
  • High-Pressure Durability: Withstands extreme pressures and temperatures using FKM (fluororubber) and nitrile rubber materials, ensuring long-term reliability.

Key features

  • 1. Material Technology

    • With a corrosion-resistant FKM (fluoroelastomer) and nitrile rubber composite reinforced by a durable outer ring, you can ensure long-lasting performance in harsh hydraulic environments, resisting extreme temperatures and aggressive fluids better than standard rubber seals*.

  • 2. Interactive Design

    • With a dual-lip design, you can prevent fluid leakage and reduce wear in high-pressure systems, maintaining operational efficiency even under continuous mechanical stress*.

  • 3. Performance Parameters

    • With a pressure tolerance of up to 20% higher than conventional seals*, you can achieve reliable operation in heavy-duty machinery like engines and pumps, ensuring minimal downtime.

  • 4. Scenario Solutions

    • With customizable dimensions and material compositions, you can adapt these seals to fit diverse industrial and automotive applications, from compact engines to large-scale hydraulic systems*.

  • 5. Certification Standards

    • Compliant with ISO 3744 hydraulic seal standards*, these seals meet rigorous safety and performance criteria for use in critical machinery, ensuring regulatory alignment and operational reliability.

Supplier's note

  1. Technical Breakthroughs:

    • Dual-Lip Design: Reduces wear by 40% compared to single-lip seals.
    • FKM Material: Triple the chemical resistance of standard rubber, ideal for corrosive fluids.
    • Pressure Tolerance: Pro Model handles 30% higher pressures than industry benchmarks, enabling use in ultra-heavy machinery.

  2. Version Selection Guide:

    • Base Model: Suitable for standard hydraulic systems (e.g., agricultural equipment) where cost efficiency is prioritized.
    • Advanced Model: Optimal for industrial pumps and engines requiring heat resistance up to +180°C.
    • Pro Model: Designed for extreme conditions (e.g., oil rigs, aerospace) with its 6500 PSI rating and +200°C tolerance.

With FKM material, you can ensure durability in chemical environments. The Pro Model’s pressure rating enables safe operation in high-stakes applications like deep-sea drilling. Pair its premium material with dual-lip design to eliminate leakage risks entirely.
