O-ring for Emag on/off

[DeuceSV]

I have an x-valve for my Emag that has no o-rings at the bottom of the on/off assembly. So, I ordered the quad-o-rings off AGD, but what other o-ring is needed that either goes ontop of below that quad-ring? My on/off piece is complete with orings and everything, so i just need to know what goes into the valve before the on/off.


thanks,
Jason
