Features: Brand new and high quality Quick Replacement: When replacing the Revo nozzle, there is no need for complicated documents and tools, just tighten the Revo nozzle by hand, and you can start 3D printing, allowing users to resume printing in a short time. Intuitive user interaction is appreciated by many 3D enthusiasts. Good Performance: The Revo nozzle is made of high-quality brass, the inner wall of the nozzle is smooth and burr-free, and the viscosity coefficient is small, which can provide you with smooth extrusion, not only suitable for ordinary 1.75mm 3D printer wire, but its wear resistance allows you to print Advanced composite materials without causing any wear and tear. Precise Design: The integrated design of the nozzle and the throat makes the possibility of material leakage zero. Each Revo nozzle comes as a pre-assembled nozzle and HeatBreak, so there is no dangerous heat tightening and no possibility of misassembly. Quick Identify: Identify nozzle size at a glance with the color-coded silicone sleeve. We provide you with a 0.4mm nozzle, fully compatible with BIQU H2 V2S revo extruder. Each Revo Nozzle is a preassembled nozzle and HeatBreak in one unit, so there's no hazardous hot tightening and no chance of incorrect assembly. Say goodbye to frustrating HotEnd leaks and enjoy reliable 3D printing!
