The Seal Ring, charger (721 133) seals critical turbocharger interfaces against exhaust and oil leakage. Replacing it with a Porza-quality gasket restores proper boost efficiency and protects the turbo system from premature wear.
A seal ring for a charger (turbocharger or supercharger) is a sealing component used within or around the unit. Its function is to prevent oil or air leaks, ensuring proper pressure, lubrication, and efficient operation of the charger system.
Key specifications include inner and outer diameter, thickness, material (such as heat- and oil-resistant rubber, metal, or PTFE), temperature resistance, and compatibility with the charger system. It must withstand high temperatures, pressure, and rotational forces.
Replacement is necessary when the seal is worn, hardened, or leaking. Common symptoms include oil leaks, loss of boost pressure, reduced engine performance, or unusual noise.
Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.
Porza provides high-quality turbocharger and engine components with fast delivery across Europe and options for online ordering or in-store pickup.
If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
