Nicely made union
Nicely made unions make crossing an airline through a bulkhead quick and easy. I got these to punch through a plastic project box but there's enough thread on there to get through a quarter inch, easily. No leaks on 6mm OD line. They work well and were reasonable priced.

works for a 3d printer
I grabbed these for use with the 4mm OD PTFE tubing used on my Prusa printer so that I could make a custom rack for holding spools and feed it into my MMU3.These fit the stock tubing perfectly. As far as fit from end to end, thats going to be something each person has to do to taper the PTFE, but this will work and works for me.

Worked well
Purchased the DIY Filament Dryier, which worked perfectly for the PTFE tubing.

Awesome for making a multi-spool 3d filament dry box
You can find gasketed tupperware containers and use these as bulkhead fittings for 3d printer tubes to keep the filament dry and clean. They screw in from both sides and work well for fitting on both sides of the container.
