1. It can effectively inhibit consumables from adhering to the nozzle surface and prevent wire drawing.2. Tight joints and flat contact surface to solve the leakage problem of consumables3. Cut chamfering, reduce resistance, reduce cold cutting Angle resistance, and discharge more smoothly4. Overall hardening treatment, high temperature resistance, corrosion resistance, smooth wire delivery5. The appearance engrave the word clearly, lets you have the good discrimination, the detail place sees the qualityName : Clone CHT Nozzle with PTFEFilament Diameter : 1.75mmScrew : M6 ThreadMax Printing Temperature : 300Thermal Conductivity : 105W/m.kHardness : 3.0 MohsApplicable Material : PLA, ABS, TPU, etc.NOTEthis nozzle support high speed printing , we already test it. But it's just a nozzle , if your extruder Extrusion ratio is low or NOT high-speed print Extruder , then this function can't be use.Colour:black+goldMaterial:Brass+PTFE coatingSize:0.6MMPackage Contents:5 x NozzleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
