Description
Technical Overview & Product Details
O-rings in marine diesel applications are subjected to harsh conditions, including constant high-frequency vibration, severe thermal cycling, and exposure to aggressive fluids like engine oil, cooling water, and fuel. The 136600-42040 is manufactured from high-grade elastomeric material selected specifically for its chemical resistance and “memory” (compression set resistance), ensuring the seal remains effective throughout its entire service life.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 136600-42040.
- Component Type: O-Ring (Seal).
- Material: High-performance, heat- and chemical-resistant synthetic rubber (optimized for the specific temperature and pressure ratings of the application).
- Application: Precision sealing for engine coolant, oil, or fuel system interfaces.
Key Features & Performance
- Reliable Sealing: Engineered to form an airtight and fluid-tight barrier, preventing pressure loss and contamination.
- Superior Elasticity: Retains its sealing force even after extended periods of thermal compression and expansion.
- Vibration Resistance: Designed to hold its position and maintain its seal integrity amidst the intensive mechanical vibrations of marine diesel propulsion.
- Precision Engineering: Manufactured to exact dimensional standards to ensure a correct “squeeze” within the housing groove, avoiding both over-compression and insufficient sealing.

- Complete Overhaul Support: We supply these O-rings alongside cylinder head gaskets, liners, and other sealing hardware to facilitate a professional, complete engine rebuild.
Technical Maintenance Note:
To ensure the maximum lifespan and performance of the 136600-42040:
- Groove Cleaning: Before installation, the seating groove must be thoroughly cleaned of all old residue, debris, and corrosion. Even minor contaminants can prevent the O-ring from seating correctly and lead to premature failure.
- Avoid Sharp Tools: Always use a plastic tool or a non-marring probe to seat the ring. Never use a metal screwdriver or sharp pick, as even a microscopic scratch on the seal groove or the ring itself can create a leak path.
- Lubrication: Use a light coat of clean assembly oil or an appropriate O-ring lubricant if the Yanmar service manual directs it, to help the ring slide into position without twisting or binding.
- One-Time Use: Never reuse an O-ring. Once installed and compressed, the material has undergone permanent deformation and cannot reliably re-seal.
