Seals and O-rings are important components used to ensure a tight connection and seal in the engine's oil circuit. They are used in various areas of the engine, such as on oil pumps, oil filters, oil drain plugs or oil filler caps.
These seals and O-rings are made of high-quality materials such as rubber or special elastomers that are highly resistant to oil, heat and pressure. They ensure that the oil stays in the circuit and does not leak, which enables efficient lubrication of the engine.
When maintaining the engine, it is important to inspect the seals and O-rings regularly and replace them if damaged or worn. A good seal in the oil circuit is crucial for proper lubrication of the engine and prevents leaks that could lead to oil loss and possible engine damage.
