1、LOWEST FRICTION: PTFE tube have the lowest friction on the market, and reliable excellent corrosion resistance 2、MORE ACCURATE PRINTING: Less friction means higher responsiveness, less retraction, more accurate printing, less extruder slippage, wear and tear, and less clogging when printing thick filaments(such as some wood fillers or iron filling) 3、PREVENT MALFUNCTION OR THERMAL CREEP: PTFE cutter and a particularly of sharpness razors are also included to ensure that the PTFE tube is cut flat on both sides to prevent any malfunction or thermal creep during feeding and retraction 4、WITH PNEUMATIC CONNECTORS: Come with PC4‑M6 and PC4‑M10 pneumatic connectors, used to fix PTFE tube on the extruder and hot end 5、98CM TOTAL TUBE LENGTH: Total tube length of remote feeding kit is 98cm, which is enough for you to use on 3D Printer
