    Seal Ring, oil drain plug

    The Seal Ring, oil drain plug (21030000) seals the oil pan for safe and leak-free engine lubrication. Replacing a worn plug with Porza quality prevents oil loss and protects the engine.

    FAQ

    A seal ring for an oil drain plug is a sealing component placed between the drain plug and the oil pan. Its function is to prevent engine oil leaks and ensure a tight seal after oil changes.

    Key specifications include inner diameter, outer diameter, thickness, material (such as copper, aluminum, or rubber), and compatibility with the drain plug. It must withstand oil exposure, pressure, and temperature changes.

    Replacement is recommended at every oil change, as the seal ring can deform after tightening. A worn seal can lead to oil leaks.

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

    Porza provides high-quality maintenance 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.
