Description
Technical Overview & Product Details
In the complex architecture of a medium-speed marine diesel engine, maintaining a perfect seal at every junction is non-negotiable. The 24326-000400 O-ring is engineered to provide a resilient, long-lasting seal in static or semi-dynamic applications where fluid pressure and thermal stress are constant factors. Whether used in cooling, lubrication, or fuel-related circuits, this component ensures that system pressures remain stable and contaminants are kept out.
- Compatible Engine Type: Yanmar 6N18 (A)L-V series marine propulsion and auxiliary engines.
- Part Number / Designation: 24326-000400 (O-Ring 4D G40).
- Component Type: High-Pressure/High-Temperature O-Ring.
- Material: Premium synthetic elastomer (Viton/FKM-grade) engineered for excellent chemical resistance and thermal stability.
- Application: Versatile sealing for various engine components (manifold connections, pump housings, and fluid lines).
Key Features & Performance
- Reliable Sealing under Pressure: Designed to withstand the high-pressure environments found within marine engine fluid circuits, preventing leakage and ensuring system efficiency.
- Thermal Endurance: Formulated to retain its elasticity and sealing force despite the continuous exposure to engine heat, preventing the material from becoming brittle or cracking over long operational cycles.
- Chemical Compatibility: Resistant to degradation from marine diesel oils, lubricating oils, and common engine coolant additives, ensuring that the seal does not swell, soften, or dissolve when in contact with system fluids.
- Standardized Precision: Manufactured to the exact dimensions of the “G40” 4D specification, ensuring a perfect fit into grooves to eliminate the risk of extrusion or pinching during installation.
Why Source from Heybeli Marine?
Using non-standard or low-quality seals can lead to coolant leaks, oil loss, or even catastrophic fire risks if a seal fails in a high-pressure line. Heybeli Marine protects your vessel’s integrity with:

- Quality Assurance: Every batch is verified for material composition and dimensional accuracy, ensuring that you receive a seal that will perform reliably from the moment of installation.
- Comprehensive Maintenance Kits: We provide these O-rings as part of our specialized 6N18 maintenance kits, streamlining your procurement and ensuring you have every seal required for a complete job.
Technical Maintenance Note:
When installing the 24326-000400 O-ring, cleanliness is critical. Ensure the O-ring groove is free of dirt, old gasket material, or corrosion. We recommend lightly lubricating the O-ring with a compatible clean fluid (either oil or grease, depending on the application) to facilitate proper seating and prevent the ring from rolling or twisting as the housing is closed. Always replace O-rings with new units during any overhaul—never reuse an O-ring, as its ability to provide a pressure-tight seal is compromised once it has been compressed and aged in service.
