Valve oil seals are the sealing elements of the gas distribution mechanism of an internal combustion engine (internal combustion engine). The part is mounted on the valve stem and in the area of ​​the guide sleeve. Thus, the element ensures the correct entry of engine oil into the combustion chamber of the engine. Thanks to the valve oil seal, there are no grease leaks; it does not get on the stem and into the combustion chamber itself during intensive vehicle operation.

The construction of the valve stem seal ring

Structurally, the DT Spare Parts brand Seal Ring, valve stem is a rubber product. As a material, a special rubber is used, which provides the necessary seal. When the valve is closed, the stem is at its highest point, causing oil droplets to fall onto the valve surface. When the manifold is opened, the stem is lowered and the lubricant enters the combustion chamber. Valve seals act as oil scraper devices, as they clean the surface of the stem from oil due to the tight fit of the rubber.
