High Quality Engine Valve Stem Oil Seal OEM RE31617 FKM Valve Seal Auto Spare Parts for John Deere

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Leak Prevention: Designed to seal valve stems in engines, preventing oil or coolant leakage into the combustion chamber to maintain engine efficiency.
  • Material Durability: Constructed with FKM (Viton®-grade) rubber and stainless steel, ensuring resistance to high temperatures, pressures, and harsh engine fluids.

Key features

  • 1. Advanced FKM Rubber Material Technology

    • With FKM (fluoroelastomer) rubber construction, you can achieve superior resistance to high temperatures, oil, and chemicals compared to standard nitrile or silicone seals.

  • 2. Precision OEM Design for Seamless Fit

    • With an OEM-specific design engineered for John Deere engines, you can ensure a precise fit and effortless installation/removal via threaded stems, avoiding leaks common in generic aftermarket seals.

  • 3. High-Performance Under Extreme Conditions

    • Withstanding temperatures up to 250°C and high-pressure engine cycles, you can maintain reliable sealing performance even in demanding commercial or agricultural applications.

  • 4. Tailored for Commercial Engine Reliability

    • Designed explicitly for John Deere engines, you can prevent oil consumption and combustion chamber contamination, ensuring prolonged engine efficiency in heavy-duty machinery.

  • 5. Compliance with Automotive Industry Standards

    • Meeting OEM certification requirements, you can trust these seals adhere to rigorous automotive quality and safety standards for professional-grade durability.
