Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sealing Performance: Designed to ensure airtight and pressure-resistant seals in diesel engine injectors, preventing fuel leakage and maintaining optimal engine efficiency.
  • Compatibility: Features two elastomeric seal rings (black and purple) in different sizes to fit specific components of CAT Diesel Engine models (C7/C9, C9 Actuated Pump, CAT3126, CAT3508, CAT3412E).

Key features

  • 1. Material Technology

    • With corrosion-resistant elastomeric material, ensure durable sealing in high-temperature diesel engine environments. The flexible rubber-like composition withstands fuel exposure and mechanical stress, outlasting standard seals*.

  • 2. Performance Parameters

    • With precision-engineered size variations (black and purple rings), achieve seamless compatibility with CAT C7/C9, Actuated Pump, and other specified engine models. The scalable design accommodates diverse component dimensions for accurate fitment*.

  • 3. Scenario Solutions

    • With reinforced sealing capability, maintain optimal performance under continuous high-pressure conditions in commercial diesel engines. Designed for heavy-duty applications like CAT3126/3508/3412E models, ensuring reliability in industrial settings.

  • 4. Certification Standards

    • Compliant with OEM diesel engine standards, guaranteeing safety and efficiency in critical engine systems. Meets industry requirements for fuel compatibility and durability*.

  • 5. Interactive Design

    • With color-coded identification (vibrant purple/black), simplify installation and maintenance by quickly distinguishing between seal sizes and applications. Reduces errors in complex repair processes.

Supplier's note

  1. Technical Breakthroughs:

    • Material Upgrade: FKM in Pro models triples chemical resistance vs. industry baselines, enabling use in high-sulfur diesel environments.
    • Color Customization: UV-stable pigments allow branding without compromising sealing integrity.
    • Size Scalability: ±0.1mm tolerance precision ensures compatibility with CAT’s tight engine tolerances.

  2. Version Selection Guidance:

    • Base Model: Ideal for routine maintenance in standard CAT engines (e.g., CAT3126).
    • Advanced Model: Suitable for harsh environments (e.g., CAT3412E marine engines) needing broader temperature adaptability.
    • Pro Model: Required for heavy-duty applications like CAT3508 power generation systems, where extreme pressure and fuel compatibility are critical.

*Pro model exceeds SAE J2064 Class B ratings by 30%.
**Custom specs require 72-hour lead time.
