The Seal Ring, injector shaft (554.975.010) ensures a leak-free seal between the injector and the engine. Replacing worn seal rings restores proper combustion pressure and prevents fuel leakage.
A seal ring for an injector shaft is a sealing component used around the injector shaft to prevent fuel, oil, or combustion gases from leaking. Its function is to maintain proper pressure within the fuel injection system and protect surrounding engine components from contamination.
Key specifications include inner and outer diameter, thickness, and material type. Seal rings are typically made from fuel- and heat-resistant materials such as nitrile rubber (NBR), fluorocarbon (FKM/Viton), or similar elastomers. They must withstand high temperatures (often up to +120°C or higher) and exposure to fuel, pressure, and vibration while maintaining elasticity and sealing performance.
Replacement is necessary whenever the injector is removed or serviced, or when signs of leakage or wear are present. Symptoms of a faulty seal may include fuel or oil leaks, reduced engine performance, or contamination around the injector area. Installing a new seal ensures proper system integrity.
Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the seal ring matches the correct injector type and dimensions, reducing the risk of incorrect fitment.
Porza supplies high-quality fuel injection and sealing components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This ensures quick and reliable access to essential parts for both professional workshops and individual users.
If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
