Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Leak Prevention: Designed to seal the front gear cover and crankshaft in diesel engines, preventing oil leakage under high-pressure and high-temperature conditions.
  • Dual-Lip Seal Technology: Features a double-lip configuration made of durable materials like Viton or Nitrile rubber to ensure robust sealing against fluids and gases while resisting contaminants.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a corrosion-resistant metal outer ring and Viton-based inner lips, ensure durability in harsh engine environments. The double-lip design offers superior resistance to chemical exposure compared to single-material seals*.

  • 2. Dual-Lip Interactive Design

    • With a dual-lip configuration, prevent fluid leakage and contaminant ingress, enhancing seal longevity compared to single-lip designs*. The flexible inner lips adapt to shaft movement for reliable sealing in dynamic engine conditions.

  • 3. High-Performance Parameters

    • With high-pressure and high-temperature tolerance, operate reliably in diesel engines under extreme conditions*. Designed for applications up to [X] PSI and [Y]°C, outperforming standard seals in harsh environments.

  • 4. Customized Scenario Solutions

    • With customizable material and lip configurations, adapt to diverse diesel engine models like 1.0 m900a_ and ACE series*. The modular design ensures compatibility with both commercial and industrial machinery demands.

  • 5. Certified Industrial Standards

    • Built to meet OEM standards for diesel engine components, ensuring compatibility and safety*. Complies with industry regulations for fluid containment and operational reliability.

Product details

4319020 DCEC QSX15 Engine Front Gear Cover Oil Seal Front Crank Seal Hydraulic Cylinder Gland Covers

The 4319020 DCEC QSX15 Engine Front Gear Cover Oil Seal is a robust double-lip mechanical seal engineered for diesel engines in CASE, AC, and Standard models (ACE, PC, Standard). Designed to withstand high-pressure and high-temperature environments, it prevents fluid leakage and contamination in critical engine components like hydraulic cylinders and crank seals.

Supplier's note

  1. Technical Breakthroughs:

    • Double-Lip Design: Reduces leakage risk by 50% compared to single-lip seals.
    • Viton Lips: Triple the temperature tolerance of traditional Nitrile seals.
    • ISO/API Compliance: Ensures seamless integration with global engine standards.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard diesel engines (e.g., CASE ACE) operating in moderate environments.
    • Advanced Model: Choose for high-temperature applications (e.g., AC PC models with frequent thermal cycling).
    • Pro Model: Required for extreme conditions (e.g., Standard 1.0 M900S engines handling corrosive fluids).

With the Pro version’s 250 bar pressure capacity, you can safely operate in heavy-duty machinery like industrial pumps. Pair its Viton lips with ISO 14001 compliance to ensure zero leakage even under prolonged stress.
