O-ring sizes for Huma Leshiy 12 FPE Regulator

I tried emailing Huma-Air directly a few days ago in regards to their o-ring sizes for their Leshiy 12ft.lb HFT Regulator but they haven't got back to me possibly due to COVID 19. I know they sell the complete o-ring kit but I want to individually purchase them to save some cash and have them on hand. I tried doing a search but came up empty handed. Does anyone know the sizes for the outer, inner and piston o-rings?


 
Nevermind guys lol. I just received an email from Huma-Air. I'm still waiting for a response for the 2 piston o-ring sizes. Hopefully if someone does a search, they'll stumble on this thread.
