I didn't receive an O-ring with mine either. Just rebuilt it with Ti and the vape is incredible - full of flavor. I am a bit confused, though. I connected it to my ipv4 and it kept reading Dry Coil, although the coil was saturated. Moved it over to my rDNA40 and had no issues. This is the first time I've used Ti wire - any suggestions?
I just did my first titanium coil too. Nice thick 24 AWG and used the Scottish Roll wicking method and now all my flooding issues are gone. I hardly have to open the juice control at all
Sorry can't help about the IPV4, titanium works fine on DNA40 and iStick TC40W both at 160C (320F).
