Review on High-Quality Creality Capricorn Filament Pneumatic Fittings: A Must-Have for Smooth 3D Printing! by Travis Caminiti

later This kit is generally of good quality if you absolutely need new tubes. If you want to get this kit as an "upgrade" just save your money. The included connectors are identical to the standard Ender 3 printer connectors and don't even grab the pipe. These fittings cause the pipe to move in and out of the fitting jaws approximately 2mm. See attached video. The tube itself is good because it has a very limited path for the filament, which reduces filament binding and results in more precise extrusion, or at least it would be if "improved fittings" weren't just your sump standard. fittings. The hose has a smaller outside dimension than the fittings can clamp. So if you don't change the end of the hose after you cut it, it just won't stay in the fitting. If you want it to fit you will need to take a lighter and melt the end of the tubing until the tubing shrinks a bit and becomes a thicker round end. In general the hose is fine, the fittings are sub-standard and this kit is by no means an upgrade.
