Caydo PTFE grommet

This is a basic grommet that secures snug with a threaded nut. The top where the pneumatic straight fitting joint goes is not threaded but the fitting easily threads into the grommet. The base of the nut where the filament enters is beveled so it loads and feeds easily. The inner diameter of the grommet is narrow enough to guide the filament into the fitting for easy loading. So far this has worked very well for me and I hope it works for you too. Feel free to make it your own!
