Hello folks,

I just got one of these dlc yftk kayfuns, and was wondering of the ultem/pei tank section is supposed to fit into the metal part without orings? I'm using it right now without orings because it came like this, no leaks so far, but I'm still wondering if the original is like this, without orings.

This one for example comes with threaded pei tank section (SKU 9630407), I'm really confused wether there is different versions or not.

Thank you guys
