Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Engine Valve Sealing: Designed to ensure airtight and leak-proof performance in SeaDoo Jetski engines, preventing fluid or gas leakage through durable rubber seals at both ends.
  • Durability & Resistance: Constructed from corrosion-resistant metallic materials (aluminum/stainless steel), optimized for harsh marine and engine environments.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a durable aluminum/stainless steel body, you can ensure long-lasting performance in marine environments, resisting corrosion from saltwater and harsh conditions.

  • 2. Secure Threaded Design for Easy Installation

    • With the threaded base and flange design, you can achieve precise alignment and secure mounting, reducing installation errors compared to non-threaded alternatives.

  • 3. OEM-Engineered Precision for Optimal Performance

    • With exact OEM specifications (part 420851754), you can restore factory-level engine efficiency and durability, outperforming generic replacements in power output and reliability.

  • 4. Marine-Grade Sealing for Leak Prevention

    • With dual rubber seals and a corrosion-resistant body, you can prevent leaks and maintain structural integrity in high-stress watercraft applications, unlike standard parts not rated for marine use.

  • 5. Certified Compatibility for SeaDoo Models

    • Certified to OEM standards, this part ensures seamless compatibility with SeaDoo Jetski Spark models, avoiding fitment issues common with non-OEM alternatives.
