On/Off O-Rings Not Seating Correctly

[ThePixelGuru]

OK, so sort of a weird problem here. The two o-rings under the on/off top (the teflon on/off o-ring and the power tube o-ring that it fits inside) don't seem to flatten out quite right in my Minimag. Seems like the teflon one won't stay inside the other. I can push the on/off in and it pops out a little as soon as I let go. I currently have a rubber band holding the on/off in so it'll hopefully stay once I take it off. Anyway, how can I get both o-rings to stay put in there? And if I can't, will it affect performance?

are you sure you have the regular power tube oring and not the level 10 power tube oring (which is smaller)?

This is my only guess.

[ThePixelGuru]

Don't own a level 10, so no. The really weird thing is that I took my Minimag apart to clean it like I have a million times, stuck it all back together in exactly the same order with exactly the same parts that I took out and now it doesn't fit right. This has never happened to me before. I suppose I could try swapping o-rings between my 'mags and see if that works...

[athomas]

The outer oring usually isn't that tight. Are you sure you have the correct one?

[ThePixelGuru]

Pretty sure. Then again, everyone who puts stuff back together and comes on here with a problem is pretty sure they put it together right. Don't see how I could have screwed it up, though, but I'll check when I get home.

Just to confirm my suspicions: This'll cause it to leak like crazy when I air it up, right? Cheers.

[athomas]

If the bolt gets pushed forward due to the on-off top not sealing properly it will leak out the front. If you push the bolt back into position, it should stop leaking.

[ThePixelGuru]

OK, problem solved. I think. I swapped the power tube o-ring with the one in the power tube, and the teflon o-ring still popped out. So I swapped that o-ring with the other teflon one in the on/off, and it fits fine. Won't know until I air it up, but it seems like that did the trick. And yes, to my best visual inspection, both o-rings that I swapped were exactly the same and fairly new (rebuilt the 'mag last year).

Weird.

[athomas]

Hopefully it works out. Maybe something caused the oring to become deformed.
