Description
Technical Overview & Product Details
As part of the JIS P-series, the P24 size is a common standard in Japanese marine engineering for sealing housings, cooling water lines, and fuel system connectors. The 24316-000240 is built to withstand high internal pressures and the thermal fluctuations inherent in a medium-speed diesel engine, ensuring that fluids remain contained and external contaminants are excluded from critical areas.
- Compatible Engine Type: Yanmar 6N18 (A)L-V series marine propulsion and auxiliary engines.
- Part Number / Designation: 24316-000240 (O-Ring 4A P24).
- Component Type: JIS P-Series Industrial O-Ring.
- Material: High-grade, heat-stabilized synthetic elastomer (FKM/Viton-grade) offering superior resistance to chemical degradation and thermal set.
- Application: Static sealing for fluid transfer interfaces, pump housings, and manifold connections.
Key Features & Performance
- Resilience Under Load: The elastomer composition is engineered to resist “compression set,” maintaining its circular cross-section and sealing force even after thousands of hours of service.
- Chemical Compatibility: Provides excellent resistance to the corrosive and solvent effects of marine-grade diesel fuel, lubricating oils, and common rust-inhibiting coolants.
- Precision Fit: Manufactured to the exact JIS P24 dimensional standards, ensuring the correct amount of mechanical “squeeze” when installed, preventing leakage pathways.
- Thermal Endurance: Specifically formulated to maintain elasticity at the elevated temperatures encountered in engine rooms, preventing the embrittlement that often leads to leaks.
Why Source from Heybeli Marine?
A small, faulty seal can lead to significant oil or coolant loss, potentially causing engine overheating or environmental concerns. Heybeli Marine ensures:
- Strict OEM Interchangeability: Our 24316-000240 O-rings meet or exceed Yanmar’s original material and dimensional specifications.
- Global Strategic Logistics: We maintain a ready-to-ship inventory of essential sealing components, ensuring rapid dispatch to your vessel or shipyard, wherever your operations take you.
- Quality Assurance: Every batch undergoes dimensional verification and material consistency checks to guarantee reliable performance under continuous marine duty.
- Comprehensive Maintenance Support: We provide these O-rings as part of our specialized 6N18 engine maintenance kits, ensuring that your overhaul is complete and reliable.
Technical Maintenance Note:
For a perfect seal, the mounting groove must be clean and free of burrs or old gasket remnants. When installing the 24316-000240, apply a thin, compatible film of lubricant to the O-ring to ensure it sits smoothly without twisting or stretching during assembly. Always use a new O-ring—reusing an old, heat-hardened seal is a primary cause of leaks. Once an O-ring has been compressed in a system, its sealing ability is permanently compromised.
