[Compatible]Our high temperature nozzles with hotend heater block can only suitable for 3 V3 SE/ 5 S1/ 7 3D Printer. Please confirm your 3D printer model before buying. The package include 5pcs 0.4mm nozzles [Premium Quality]nozzles, good abrasion resistance, heat resistance, and resistance. No burr on the orifice makes the feeding of the filament smoother and no leakage, the tight connection effectively avoid the problem of [High-Temperature Resistance]The max temp of this hardened steel nozzle could reach 500c, suitable for 3D printing at high temperatures, It is Suitable for most materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., [Precise Design]Each side of the 3D printer nozzle is cut by a diamond knife, so its contact is flatter. The extruder nozzle can effectively prevent the print head from leaking and produce a smooth, bright and consistent printing effect. Name : 3D Printer Nozzle.
