    FAQ

    A seal ring for a coolant hose is a sealing component used at the connection points of hoses in the cooling system. Its function is to ensure a leak-free connection, preventing coolant loss and maintaining proper system pressure.

    Key specifications include inner and outer diameter, thickness, material (such as rubber or heat-resistant elastomer), temperature resistance, and compatibility with the cooling system. It must withstand heat, pressure, and coolant exposure.

    Replacement is necessary when the seal is worn, hardened, cracked, or leaking. It is also recommended to replace it during cooling system maintenance or when hoses are removed.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality cooling system 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.
