The Fuel Filter Seat Disk spring is designed to exert pressure on the seat disk, ensuring a tight seal within the fuel filter assembly. It maintains consistent pressure to prevent fuel leakage and maintain optimal filtration efficiency. The spring's function also allows for flexibility, accommodating variations in filter element thickness and ensuring secure seating. Its reliable performance enhances the fuel system's integrity and contributes to smooth engine operation.Attributes:• Resistant to wear and tear from constant movement.• Corrosion-resistant materials for extended lifespan.• Total coils is 8 and active coils is 6.• The direction of the coils is right hand.• Endures permanent deformation under load.Applications: The Fuel Filter Seat Disk Spring ensures proper seating of the fuel filter disk, preventing leaks and maintaining consistent fuel flow in the system.
