oring

Before I order the newer kayfun 5 squared second edition I'm trying to order oring replacements, since I'm ordering extras for a taifun, but I can't find the correct sizes. I see sizes on svoemesto for the first edition but not the SE. Does anybody know where I can find the correct sizes?

Would anyone know the o-ring measurements for the deck and at the delrin chuff cap? I'm trying to go a size lower. I'm having a hard time seating the chuff cap and the barrel on this atomizer.

I have seem a few people asking about replacement PT coil rubber grommets. I had some free time today to run through Home Depot. I found the following o-rings 10 pack for 2.27 plus tax. I tried it on my PT2 coil and fresh made EVOD coil with cotton wicks. Both working good, no leaks. Hope...

With the need to screw the mouthpiece on and off to refill, I've lost the oring that keeps the seal tight. Anyone have a source for replacements?
