Notos barrel o-rings

[Raptor72]

What size outside barrel (transfer port) orings are you using for replacement?
  It calls for .8x10.2 mm. I have a few closest I could find on order but surely you guys already have one that works.

  Forgiveness if it’s been discussed- Does a pp750 barrel fit the Notos without much modification? I have a factory one that’s not so accurate with all pellets I’ve tried.

 Also is anyone printing original length baffles that seem to be quieter than factory?
 Thanks for any input.

 I did check w/Umarex for replacement parts and that’s a no go for me anyhow. What Spa/Art parts interchange?

This M0.8 x 8.4 size works perfectly:

SPA's exploded diagrams list O-rings by their OD, against industry standard practice.  The above O-ring is a M0.8 x 10.0 by SPA's way of calling it out.

Thanks Jason, I do have that size ordered. 😎

Andrew, did you get this sorted out?
 
Reason I’m asking, someone on another board posted measurements of the Notos O-ring and it’s larger than the M0.8 x 8.4 used on other SPA barrels.  Looks like it may instead be the M0.8 x 10.2 size that you posted so I’m hoping you can chime in.

Exactly why I don’t own guns anymore that don’t have parts or support I just don’t care to deal with it.

I never could source the .8x10mm orings but I’m using 1x9mm I.D. and seem to getting the job done.

Very good, thank you for the additional information, and for replying so quickly!

Someone found them on AliExpress, I ordered 100 so I should have stock in a month.
