QiDi Max4 Hotend Silicone Sock Protector (5pc) OEM

This 5-piece hotend silicon sock features industrial-grade silicone formulated to withstand 300°C thermal environments. The sock maintains precise heat retention around the nozzle assembly whilst resisting mechanical stress and chemical degradation from molten filament. Minimises heat loss from ambient airflow and prevents plastic accumulation, extending nozzle service life across high-temperature printing work-flows.
