As a manufacturer with over a century of tradition, QUICKSILVER guarantees the highest quality materials resistant to high temperatures and the action of operational fluids. This part functions as a simmer ring, a dynamic seal that protects against leaks and the ingress of contaminants into the mechanism.

Installation and Operational Tips

Proper installation of the O-ring is a guarantee of your engine's long lifespan. When replacing the seal, pay attention to the cleanliness of the sealing groove surface. Even the smallest scratches or contaminants can lead to leaks. Before installing the new QUICKSILVER O-ring, lightly lubricate it with clean engine oil or silicone grease to prevent twisting or cutting during assembly. Do not use aggressive solvents that can damage the rubber. Regular inspection of seal conditions prevents costly failures and extends the life of the propulsion unit.
