Agwuoetr 3Pcs Mk10 Silicone Socks Instead Ceramic Insulation For Dupicator D4/I3/for I3 2 Silicone Heater Block Cover

Helps to keep the hotend temperature extremely stable, particularly if you use high-airflow cooling around the nozzle to cool the print. Made of a heat-, non-stick silicone material our socks repel build-up of molten plastic. This really helps with sticky materials like co-polyesters and filled-composite materials that like to build up on nozzles. The covers simply push onto the front of the Hot End with no disassembly - they be a tight fit when first pushed on cold. When hot the silicone expand to the correct size to fit the hotend snugly. Very useful silicone socks: keep your heater block clean and free from burnt and blackened plastic. They don't just keep the block clean, but also keep heat inside the hotend and off your print. Please kindly note: we suggest highest safe temperature resistance is about 230 Celsius-250 Celsius/ 446 Fahrenheit-482 Fahrenheit.
