Heating Rod Thermistor Set

This complete hotend upgrade kit includes a precision heating block, high-performance heating rod, accurate thermistor sensor, durable heatbreak, and three hardened steel nozzles in 0.2mm, 0.4mm, and 0.6mm sizes, making it ideal for versatile 3D printing needs. The hardened steel nozzles provide excellent wear resistance for printing abrasive filaments such as carbon fiber, glow, and metal-filled materials, while maintaining consistent extrusion and fine detail. The heatbreak ensures smooth filament transition with reduced clogging and improved thermal separation for stable printing performance. The fast-heating cartridge and sensitive thermistor deliver precise temperature control, helping achieve reliable layer adhesion and clean prints. Three silicone sleeves are included to retain heat, protect the heating block from filament residue, and maintain stable temperatures during long prints. Compatible with most MK8-style hotends such as Ender 3, Ender 5, CR-10, and similar FDM printers, this kit is a durable and efficient solution for upgrading or replacing worn extruder components
