Drain plug washer M12
Product Details

A fresh drain-bolt sealing washer goes in every single time you change oil. Reusing the old one is how you end up with a slow oil leak that wets the underside of the engine — or worse, lets the bolt back off and dumps your oil at speed.

  • Size: 12x18x1.5mm
  • Material: Aluminum
  • Use: One-time-use crush washer. Replace at every oil change.

Check your service manual for the exact spec — most Japanese 4-strokes use 12x18x1.5mm aluminum, most KTM/Husqvarna use 12x16x1.5mm aluminum, and Harleys typically use the larger 14x21x1.5mm or 29.5x33.5x1mm copper depending on application.
