Fits a normal pass-thru 4mm PTFE push fitting (1.75mm filament) on one side, and a 6mm push connect on the other, with a ramp that feeds 1.75mm filament cleanly into the smaller PTFE.
Used for running big 6mm PTFE tube for reverse bowden or drybox down to (in my case) a BMG-M that only can use a 4mm PTFE connector.
Bigger PTFE means a longer run is less drag on the filament, and it stands up nicer than 4mm.
Both sides are M10 1.0 thread. Many 6mm PTFE connectors are actually NPT thread, but it fits great anyways.
