Orings of injectors are crucial sealing components in the fuel supply system of internal combustion engines. Their main task is to ensure the tightness of connections between the injector and the fuel rail, as well as the intake manifold. These gaskets eliminate the risk of fuel leaks, ensuring the optimal operation of the fuel injection system and the precise metering of the fuel-air mixture. Injector orings must exhibit high chemical and thermal resistance. They are most commonly made of elastomers such as NBR or FKM. NBR rubber shows excellent resistance to oils and fuels, while FKM is additionally characterized by resistance to high temperatures (up to +200°C) and aggressive chemical substances, such as additives used in fuels. The use of injector orings encompasses both gasoline and diesel engines. In Common Rail systems and units with direct fuel injection, these seals play a particularly important role as they must withstand very high pressures reaching up to 2500 bar. Their wear leads to a decrease in engine performance, starting issues, and increased emissions. High-quality injector orings are resistant to aging, ozone exposure, and temperature differences. Thanks to their flexibility and precise fit to the mounting socket, they ensure long-lasting and trouble-free use. Regular inspection and replacement of injector seals are crucial to maintaining engine efficiency and reducing the risk of costly repairs.

Injector O-rings play a crucial role in the fuel system of internal combustion engines, providing a tight seal between the injector and the fuel rail as well as the intake manifold. Their use minimizes the risk of fuel leaks, resulting in optimal engine performance and precise fuel-air mixture dosing. The effectiveness of the seal is key to engine efficiency.

Regular replacement of O-rings prevents a decrease in performance, starting difficulties, and increased exhaust emissions, contributing to a longer lifespan of the fuel system.
