Drain washer selection guide
Choosing a drain washer depends on exact compatibility with your vehicle's drain plug and the reliability of the sealing material.
The washer material is a determining factor to ensure sealing. Washers made of aluminum mixed with cotton, such as those available for Toyota engines, offer thermal resistance and compression capacity suited to the demands of the lubrication circuit.
Dimensional precision is essential to avoid any risk of leakage. You should check the inner and outer diameter of the washer, as well as its length and width, to ensure it fits perfectly with the thread and contact surface of the drain plug.
The original reference (OEM) is the safest way to ensure compatibility. By cross-referencing the original part number with the washer specifications, you guarantee direct installation and optimal sealing for regular vehicle maintenance.

| Inner and outer dimensions | Check the inner diameter (e.g., 12.2 mm) and outer diameter (e.g., 21 mm) to ensure a perfect fit for the washer. |
| Original reference (OEM) | Ensure the OEM part number matches your vehicle for direct compatibility and installation without modification. |
| Length and width | Check the linear dimensions of the washer (length and width, e.g., 21 mm) to confirm it correctly covers the sealing surface. |
