Bambu Lab Hotend Silicone Sock for P1 Series / X1 Series

Bambu Lab Silicone Sock – Heater Block Cover for P1 / X1 Series

The Bambu Lab Silicone Sock is the official heater block cover replacement for Bambu Lab printers. This heat-resistant silicone sleeve insulates the heater block, improving thermal efficiency and preventing filament from sticking to the hotend.

Essential for maintaining optimal hotend performance. The silicone sock helps with temperature stability, protects the heater block from ooze buildup, and makes cleaning easier if filament does contact the hotend.
