The OEM oil screen crush washer is made of aluminum and is intended as a single-use washer. After experiencing several oil leaks from attempts at reusing the OEM washer, I sought a better option. Unfortunately, the large diameter of the washer wasn’t available, so I commissioned these custom washers. This washer will fit oil screens that look like the picture below with a 21mm hex head. This washer will fit most 2002 and earlier Ducatis. Later models came with separate screen cover/plug requiring a 14mm allen socket. These later models take a larger diameter crush washer not available from Desmo Times.
