Description
Technical Overview & Product Details
O-rings of this size are vital for maintaining the integrity of smaller fluid circuits, sensor ports, and fitting interfaces. The 24311-000110 is designed to provide a secure, leak-proof barrier, even when exposed to the high-frequency vibrations, significant thermal fluctuations, and chemical agents (oils, fuel, and coolants) typical of maritime diesel operations.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 24311-000110 (1A P11).
- Component Type: O-Ring (Seal).
- Material: High-grade synthetic elastomer (1A specification, optimized for OEM marine standards).
- Application: General engine sealing (commonly used in fluid fittings, banjo bolts, sensor housings, and small auxiliary component interfaces).
Key Features & Performance
- Reliable Seal Integrity: Engineered for a tight, leak-proof fit that maintains its sealing force under varying pressures and temperatures.
- Excellent Compression Recovery: Formulated to resist “compression set” (flattening), ensuring the seal remains effective throughout its service life.
- Chemical & Thermal Resistance: The 1A compound is specifically selected to endure prolonged exposure to engine lubricants and coolant additives without swelling, cracking, or hardening.
- Dimensional Accuracy: Manufactured to strict JIS (Japanese Industrial Standard) tolerances, ensuring a secure, perfect fit within its designated groove.
Why Source from Heybeli Marine?
A small leak in a sensor or fitting can be difficult to locate and often leads to messy engine room conditions or system pressure loss. Heybeli Marine protects your vessel’s performance with:
- Strict OEM Interchangeability: Our 24311-000110 seals are manufactured to the precise dimensional and hardness specifications required for Yanmar diesel engines.
- Global Strategic Logistics: We maintain a large, ready-to-ship inventory of these essential sealing components to ensure your maintenance schedules are met without delay.
- Quality Assurance: Every batch is verified for structural integrity, ensuring that you receive seals free of molding defects or surface irregularities.
- Complete Overhaul Support: We supply these O-rings alongside gaskets, V-rings, and other hardware to support a professional and reliable engine service.
Technical Maintenance Note:
To ensure the 24311-000110 provides a long-lasting, leak-proof seal:
- Groove Preparation: Thoroughly clean the mating groove of all old residue, debris, and oxidation. Even a tiny piece of dirt will prevent the O-ring from seating evenly.
- Installation Lubrication: Apply a thin, light film of clean engine oil or an approved assembly grease to the O-ring before installation. This facilitates smooth seating and prevents the O-ring from twisting, which is a common cause of spiral failure.
- Handling: Never use a metal screwdriver or sharp pick to install or remove the O-ring. Use plastic probes or your fingers to avoid scratching the housing or the sealing surface of the ring itself.
- No Reuse: Once compressed, an O-ring loses its initial elasticity and “memory.” Always install a brand-new O-ring whenever a component is disassembled for maintenance.
