1~5 PCS for Creality 3D Printer Silicone Sock Hotend Insulation Cover High Temp 300°C for K2 Plus K1C Hi Combo K1 Series Replacement(2 Set)

3D Printer Silicone Sock Hotend Insulation Cover

• 1.【Precision Fit for K2 Plus and K1C Series Printers】 This silicone sock is custom-molded to fit snugly over the heater block of Creality K2 Plus, Hi Combo, K1C, K1, and K1 Max 3D printers. The precise fit ensures complete coverage without slipping, providing reliable thermal protection for high-speed and high-temperature printing
• 2.【High-Temperature Silicone Rated to 300°C for Stable Hotend Temperature】 Made from durable, heat-resistant silicone rubber capable of withstanding continuous operating temperatures up to 300°C. The sock insulates the heater block to maintain stable nozzle temperature, reduce heat loss, and protect the hotend from cooling air drafts generated by part-cooling fans
• 3.【Prevents Filament Buildup and Protects Hotend Components】 The naturally non-stick silicone surface repels molten plastic, preventing burnt filament from adhering to the heater block, thermistor wires, and heater cartridge cables. This helps avoid the "blob of death" that can ruin an entire hotend assembly and makes post-print cleanup quick and easy
• 4.【Essential Maintenance Spare for Consistent Print Quality】 Over time, silicone can become brittle with repeated heating cycles. A cracked, loose, or missing silicone sock can cause temperature instability, heat creep, and filament blobs. Replacing a worn sock with this thermal protection cover helps restore proper hotend insulation, prevents clogs, and extends the service life of your hotend assembly
• 5.【Quick and Easy Installation – No Tools Required】 Simply remove the old sock by pulling it gently off the heater block, then press the new silicone sock firmly into place. The flexible material holds securely to the heating block without adhesive or tools, making it a straightforward DIY replacement for both beginners and experienced users
