Anybody have any leads for a proper sized oring to go on a Phoenix base? I'm not having leaking issues, just not getting the tightness wanted when lining up the air hole with the coil. The Trivecca from okcvapes.com came with two clear silicone rings that help but if they were just a hair thicker would be perfect. If someone could point me to the right ones or give me the size needed I'd appreciate it.
