In the demanding environment of a commercial truck, the integrity of every fluid connection is non-negotiable. As a trusted source for precision-engineered Foton truck parts, we present the essential Seal Washer, identified by the official OEM part number 612600080246. This specialized sealing component is a critical element used in conjunction with bolts, plugs, and fittings across the engine, hydraulic, and fuel systems of FOTON trucks. Designed to create a reliable, pressure-tight seal, this washer prevents leaks of oil, fuel, coolant, or hydraulic fluid, ensuring system integrity and operational safety. The correct installation of washer 612600080246 is a fundamental step in any repair or maintenance procedure.

The Seal Washer, part number 612600080246, is a deformable sealing element placed under the head of a bolt or a nut. Its primary function is to fill microscopic imperfections between the fastener and the mating surface, creating a leak-tight barrier.
When the fastener is tightened, the washer compresses and flows into these tiny grooves and scratches, effectively blocking the path for fluids under pressure. This is especially critical in systems like engine oil pans, gearbox housings, hydraulic valve blocks, and high-pressure fuel lines on FOTON trucks.
Unlike a standard flat washer, a seal washer like 612600080246 is specifically designed with sealing properties, often made from softer metals or composite materials that can deform without fracturing to achieve the perfect seal.
The seal washer 612600080246 is utilized in numerous locations throughout a FOTON truck. Common applications include sealing drain plugs on the engine oil pan, transmission, and differential housings.
It is also frequently used on hydraulic line fittings, fuel injection pipe unions, and sensor mounting points where a fluid-tight seal is required. In the cooling system, it may be found on thermostat housing bolts or water pump connections.
Using the correct OEM washer in each location is vital. The material and design are often specific to the type of fluid, pressure, and temperature of that particular system. Substituting a standard washer for part 612600080246 is a common cause of post-repair leaks.
The genuine 612600080246 washer is typically made from one of several specialized materials. Copper or aluminum washers are common for high-temperature applications like exhaust manifolds or turbocharger oil lines, as they can withstand heat and provide excellent conformability.
Composite fiber or rubber-impregnated washers are used for lower-temperature, lower-pressure sealing on covers and pans. Some washers feature a bonded rubber coating on a metal core for a combination of strength and flexibility.
The choice of material for this specific part number is determined by FOTON engineers to match the exact service conditions. The washer may also be coated with a sealing compound or have a raised bead to enhance the sealing performance further.

Proper installation of the seal washer 612600080246 is critical for its function. The sealing surfaces on both the fastener and the component must be clean, dry, and free of old washer material, rust, or debris.
The new washer should be placed squarely on the fastener or seating surface. It is crucial to tighten the fastener to the manufacturer’s specified torque using a calibrated torque wrench. Overtightening can over-crush the washer, causing it to split or extrude, while undertightening will not create sufficient sealing pressure.
Most seal washers, including part 612600080246, are designed for single use. Once compressed, they take a “set” and lose their ability to seal effectively if reused. Always install a new washer during any disassembly and reassembly procedure.
Understanding why seal washers fail helps prevent future leaks and ensures the correct use of part 612600080246.
Leak Immediately After Service: This is often due to reusing an old, already compressed washer, incorrect washer material for the fluid, or insufficient tightening torque. Always use a new, correct OEM washer and follow torque specs.
Leak Developing Over Time: Can be caused by thermal cycling, vibration loosening the fastener, or chemical degradation of an incompatible washer material. Using the specified part 612600080246 and periodically checking fastener tightness can prevent this.
Washer Distortion or Splitting: This is a clear sign of overtightening. It can also occur if the washer is misaligned or if the seating surface is damaged or uneven. Inspect surfaces before installation.
Preventive Maintenance: During routine fluid changes or inspections, proactively replace seal washers on critical drain plugs and fittings. The minimal cost of washer 612600080246 is insignificant compared to the cost of a major fluid leak or system failure.
Selecting the correct seal washer material is as important as the part number. The genuine 612600080246 washer is supplied in the material specified by FOTON for its intended application.
For engine oil and general hydrocarbons, copper or composite washers are often used. For brake fluid or certain coolants, specific rubber or fiber compositions are required. Aluminum washers are excellent for sealing in high-temperature areas but may not be suitable for all chemicals.
Never substitute a washer material based on availability alone. Using a copper washer where an aluminum one is specified (or vice versa) can lead to galvanic corrosion, improper sealing, or damage to softer aluminum components. Always use the exact OEM part.
The Seal Washer, OEM part 612600080246, exemplifies the importance of precision in even the smallest components. Its role in preventing leaks protects the vehicle’s vital systems, the environment, and your operational budget.
Investing in the genuine FOTON part guarantees the correct material, dimensions, and performance characteristics. This ensures a reliable seal that withstands pressure, temperature, and chemical exposure as intended by the vehicle’s engineers.
