Feature:
1) Throat Adapter: Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. It has High temperature resistant up to 500C degree, with different thermal conductivity and smooth inner wall reduce 3d printer material clogging. A wide compatibility with different filaments, such as PLA, TPU, PETG, Wood, ABS, etc.

2) Heater Block: Aluminum, not copper. High Temperature, high precision, stable performance.

3) Thermistor: Made of high quality material, with the imported electrical resistor mini 104NT , brassing tube, with the internal temperature package to ensure the maximum service life with precision temperature measurement. Resistance: 100(+-3%) kohms, B value: 4 267 K(+-2%) at 25/85 Degree C. A newest model, which can be for 300℃ long hours printing.(Please make sure the temp should not be over 300 °C, otherwise the temperature will not be accurate.)

4) Heating Ceremic: 24V 40W directly for stock heaters, heat fast.

5) Silicone sock: Easy to install and remove: Drop-in Replacement for the original sock. They go on just as easily as the OEM ones do, Help keep your heater block clean and repel plastic of burnt, blackened, and filament build-up, reduce your repair times, then extend the life of the heat block and nozzle, even the whole hot end. Make sure to enable the "Nextruder Silicone Sock" option under "Settings->Hardware", otherwise you might see issues with it not retracting enough to prevent crashing into your print.
