Description

Technical Overview & Product Details

O-rings are deceptively simple components that act as the first line of defense against fluid loss and contamination. The 152633-01810 is designed for high-pressure/high-temperature static applications. Its primary function is to seal interfaces where fluid or gas transfer occurs—typically within the cooling circuits, fuel systems, or lubrication lines where tight tolerances are maintained.

  • Compatible Engine Type: Yanmar 6N18 (A)L-V series marine propulsion and auxiliary engines.
  • Part Number / Designation: 152633-01810.
  • Component Type: High-Performance Industrial O-Ring.
  • Material: Premium-grade synthetic elastomer (such as FKM/Viton), selected for its excellent resistance to thermal degradation, chemical swelling, and compression set.
  • Application: Static sealing for fluid system components, including hydraulic and fuel system connections.

Key Features & Performance

  • Optimal Compression Set Resistance: Engineered to maintain its original seal geometry even after extended periods of compression at high engine operating temperatures, ensuring no leakage over long service intervals.
  • Chemical Resilience: Formulated to remain stable when exposed to diverse fluids, including marine-grade diesel, lubricating oils, and coolant additives, preventing material degradation or softening.
  • Precision Dimensional Stability: Manufactured to exact tolerances to ensure the correct interference fit within the groove, preventing extrusion and promoting a long-lasting, gas/fluid-tight seal.
  • Reliable Thermal Endurance: Specifically designed to function effectively within the high-temperature environment of a medium-speed diesel engine room without becoming brittle.

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 152633-01810 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, carbon deposits, or old gasket remnants. When installing the 152633-01810, 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.
