Bosch Fuel Injector Seal O-Ring

Bosch fuel injector seal and O-ring kits replace the worn or hardened seals that cause fuel leaks at the injector. A good seal between the injector, the fuel rail and the intake or cylinder head keeps fuel delivery consistent. It also helps prevent fuel odors, rough idle and misfires. This line is a good fit when you are servicing or reinstalling fuel injectors.

Key Features:

• Leak-resistant sealing: O-rings are made to seal the injector against its fuel rail and mounting bore, which helps prevent fuel leaks.
• OE-level quality: Bosch is a leading OE supplier of fuel system components, and these seals are built to OEM standards for form, fit and function.
• Fuel-resistant materials: The seals are made for lasting service in contact with fuel and engine heat.
• Application-specific kits: Each part number in the line matches a particular injector design. Some kits also include related hardware, such as retaining clips.
• Easy to service: Replacing the seals when you remove the injectors is a low-cost way to avoid leaks and repeat repairs.

Common signs of worn injector O-rings include fuel odor, visible fuel seepage near the injectors, rough idle, misfires and reduced fuel efficiency. Choose the child item that matches your injector for a dependable, long-lasting seal from a trusted name in fuel systems.
