Description
Technical Overview & Product Details
In the dense architecture of a medium-speed marine diesel engine, maintaining a perfect seal at every junction is non-negotiable. The 34311-000280 O-ring is designed for applications where fluid pressure and thermal stress are constant factors. Whether it is used in manifold connections, pump housings, or fluid lines, this component ensures that system pressures remain stable and external contaminants are excluded.
- Compatible Engine Type: Yanmar 6N18 (A)L-V series marine propulsion and auxiliary engines.
- Part Number / Designation: 34311-000280 (O-Ring 1A P28).
- Component Type: Standard Industrial O-Ring (JIS P-Series).
- Material: Premium synthetic elastomer (Viton/FKM-grade) engineered for high thermal stability and chemical resistance to engine oils and coolants.
- Application: Versatile sealing for static fluid-transfer interfaces.
Key Features & Performance
- Reliable Sealing under Pressure: Designed to maintain its profile under 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 continuous exposure to high-temperature engine fluids, preventing the material from becoming brittle.
- Chemical Compatibility: Resistant to degradation from marine diesel oils, lubricating oils, and common engine coolant additives, preventing swelling, softening, or dissolution.
- Standardized Precision: Manufactured to the exact dimensions of the “P28” JIS 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:
- Strict OEM Interchangeability: Our 34311-000280 O-rings meet or exceed Yanmar’s original material and dimensional specifications, ensuring 100% compatibility.
- Global Strategic Logistics: We maintain a large, consistent inventory of essential sealing components, ensuring that even small items are always in stock for rapid dispatch to your vessel or shipyard.
- Quality Assurance: Every batch is verified for material composition and dimensional accuracy, ensuring that you receive a seal that performs reliably from the moment of installation.
- Comprehensive Kits: We provide these O-rings as part of our specialized 6N18 maintenance kits, streamlining your procurement and ensuring you have every required seal for a complete job.
Technical Maintenance Note:
When installing the 34311-000280 O-ring, ensure the groove is entirely 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. Never reuse an O-ring—once it has been compressed and aged in service, its sealing capability is permanently compromised.
