Title: Notos barrel o-rings
Post by: Raptor72 on June 25, 2023, 05:28:48 PM
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.

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.

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