Silicone Sock for Elegoo Neptune 4 Plus 4 Max Hotend Heater Block Cover

• Silicone Sock for Elegoo Neptune 4 Plusand Elegoo Neptune 4 Max silicone sock is a practical upgrade for protecting your hotend heater block and improving thermal consistency during printing.
• By adding effective thermal insulation around the heater block, it helps reduce temperature fluctuations caused by cooling airflow and ambient changes—supporting steadier extrusion and more consistent layers.
• This is especially useful for longer jobs, high-speed printing, and materials that demand stable heat.
• Made from heat-resistant silicone rubber, the sock acts as a protective barrier against melted filament, dust, and debris.
• Over time, residue can bake onto the heater block and make maintenance harder; using a Elegoo Neptune 4 Plus helps keep the block cleaner, reduces buildup, and can extend the service life of hotend components
• Elegoo Neptune 4 Max silicone sock is also improves day-to-day safety by reducing accidental contact with hot surfaces when working near the toolhead.
• This model is designed as a perfect OEM fit for the Neptune 4 Plus / 4 Max, so installation is quick: slide it over the heater block and ensure it sits snugly without obstructing the nozzle tip or any moving parts. A secure fit helps it stay in place even during frequent heating cycles and rapid motion.
