【Creality Official Replacement】- This is a genuine Creality hotend silicone sock, precision-molded for a perfect fit on the SPARKX i7 heater block. Direct replacement for the original part—no modifications needed. 【Heat-Resistant & Non-Stick】- Made of high-quality, non-stick silicone rated for high-temperature printing. Prevents melted filament from adhering to the heater block, reducing burnt residue and making cleanup quick and easy.  【Thermal Insulation & Stability】- The silicone sock provides essential thermal insulation, keeping heat inside the heater block. Helps the hotend reach target temperature faster and maintain consistent heat during long prints, reducing temperature fluctuations that can cause print defects.  【Hotend Protection】- Shields the heater block from stray filament, dust, and debris. A clean heater block ensures reliable thermal transfer and prevents burnt plastic from dripping onto prints or clogging the nozzle—critical for multi-color printing with CFS Lite. 【3-Pack for Maintenance】- The sock is a consumable part that wears or gets damaged over time. This 3-pack gives you a ready supply of spares—always have a fresh sock on hand when you need to replace a worn or torn one.
