Reliable thermistor + heater replacement kit engineered for direct use with X1, P1P and P1s extruder hot ends. Restores precise temperature sensing and stable heating for consistent, quality 3D prints. Key benefits Restores printer functionality: replaces worn or damaged thermistor and heating element to get your X1, P1P or P1s back to printing quickly. Stable temperature control: accurate thermistor feedback and a matched heater cartridge reduce temperature drift, improving layer adhesion and print consistency. Hassleminimized installation: designed to match the stock extruder hot end form and connectors for straightforward swapin replacement or maintenance. Maintenance and reliability: useful as a spare part for routine service, reducing downtime and extending the usable life of your hot end. Key attributes Functionality: complete heating and temperaturesensing solution for the extruder hot end—thermistor plus heater element and wiring. Compatibility: explicitly made for X1, P1P and P1s models (designed to fit the original hot end assembly and interface). Size and fit: matched to the standard hot end dimensions used on X1 / P1P / P1s for direct replacement without modification. Materials and construction: built from durable heating element and thermistor components with insulated wiring to withstand regular use. Performance: delivers consistent heating behavior and reliable thermistor readings to support predictable extrusion and print quality. Typical use cases a failed thermistor or heater cartridge on an X1, P1P or P1s hot end to resume printing without changing the printer firmware or mounts. Keep as a spare part for scheduled maintenance so you can swap components quickly and avoid long downtime. Use when switching between filaments that require precise temperature control (PLA, PETG, ABS) to maintain consistent extrusion and surface finish. What the kit provides Thermistor, heater element and wiring configured for installation in X1, P1P and P1s extruder hot ends. Designed as a direct replacement to match the original hot end interfaces. Compatibility reminder: for use with X1, P1P and P1s extruder hot ends only. Follow your printer manufacturer's service instructions when installing replacement hot end components.
