Pro silicone socks are made to insulate the heater block and nozzle for more efficient, stable thermal performance. The pro sock goes a step further than the standard sock, covering the majority of the nozzle, leaving just the tip exposed. This makes it ideal for small nozzles sizes (0.15 and 0.25mm).
Made from an inherently non-stick high-temperature silicone, the pro sock helps keep your nozzles and block free from plastic residue.
We supply the socks in a 3 pack because while they are designed to be as durable as possible, they will eventually wear away or perish. Your mileage will vary depending on the temperatures used and the materials you print with.
