Air Intake/trumpet/velocity Stack O-ring - 748

  1. Part number 886.5.004.1A...

    While I have not got in touch with a dealer yet I am guessing they are crazy money for an o-ring.

    I have failed despite searching on here, measuring the old ones which ended up in getting some that are a tiny but too fat...now having found some measurements in inches I cannot find an o-ring that matches.

    Any pointers on where I can get some that are not bonkers money or am I going to have to bite the bullet?

    Obliged
     
  2. Online checking shows these as sub £2 from Ducati direct. Not sure on wait times but wouldn’t imagine it would be too long.
     
  3. Measure the diameter of the groove, that's your O-ring ID, Then measure the cross section of the old o-ring. Go to polymax or simply bearings and spec your o-ring with those 2 figures, ID and cross section.
    Choose the closest one if you don't find a exact match. Go slightly smaller in ID rather than larger.
     
  4. I can wait….and for that money that is reasonable

    Where do you buy online…?
     
  5. Appreciate that thanks
     
  6. Online works out expensive at £12 for a pair delivered. Best bet is ring your local Ducati dealer and see if they will Chuck a couple in an envelope for you rather than usual courier fees of £6. That or just pop past and order them in
     
  7. Great thank you...will pop into Ducati Chelmsford if I am passing or otherwise give them a bell.

    Thank you all
