High lubricity additives make XS Series tubing the lowest friction Bowden tubing on the market. Less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear and tear, and less friction when printing thick filaments such as certain wood or iron chips clogged. tube high temperature is specially designed for 2mm wire, the inner and outer diameters are extremely precise, the wire is loaded to the hot end smoothly, and the error space between the extruder and the hot end is as small as possible. Lower retraction means saving time with each retraction of the extruder. A few milliseconds here and a few milliseconds there add up to a huge time saver during printing. Also included is a cutter with an extra sharp to that both sides of the are cut flat to prevent any failure or thermal creep during feeding and retracting. The upgraded pneumatic fittings with metal teeth included in this package are much the with plastic teeth or cheap locking mechanisms that many cheap 3D printer manufacturers . color: blue Material: ABS+ aluminum alloy Package Contents: 1 x 1m tube 1 x pipe cutter 2 x PC4-M10 pneumatic connector 2 x KJH04-M6 pneumatic connector
