Product Advantages
1. OEM Standard Precision Matching：Produced in strict accordance with the original factory drawings and tolerance standards of Komatsu S6D102E engine, the inner and outer diameter, thickness and sealing edge are highly matched with the connection positions, no secondary processing is required for installation, reducing assembly errors.
2. Dual-structure Durability：The metal core ensures high structural strength and pressure resistance, and the rubber coating provides excellent sealing performance and oil resistance. The integrated molding process avoids delamination and falling off, and the service life is more than 30% longer than ordinary single-material washers.
3. Strong Adaptability to Working Conditions：Passed professional tests of high temperature, continuous vibration, corrosion and pressure change, the sealing performance remains stable in harsh working environments such as construction sites and mines, adapting to the high-intensity operation requirements of engineering machinery.
4. Wide Applicability：Suitable for multiple bolt connection and pipeline interface sealing positions of the engine, with strong versatility, and can be used as a direct replacement part for the original factory washer.
5. Easy Installation & High Cost Performance：Compact structure, simple and fast installation without special tools; the performance is close to the original factory accessories with a more favorable price, reducing procurement and maintenance costs, and lowering downtime losses caused by sealing failure.
Installation & Maintenance Tips
1. Clean the sealing mating surface and bolt before installation, remove oil stains, rust, impurities and old washer residues to ensure the surface is flat and free of scratches.
2. Install the washer in the correct direction, ensure it is closely attached to the mating surface without tilting or twisting, and then fasten the bolt according to the specified torque.
3. Do not reuse the washer after disassembly to avoid the loss of elasticity of the rubber layer and sealing failure; replace it with a new one in time during maintenance.
4. Regularly check the status of the washer, if found aging, cracking, delamination or medium leakage at the connection position, replace it in time to avoid the expansion of engine faults.
