1pc Silicone Sock Heater Block Silicone Cover MK9 Hotend Heater Protect for 3D Printer,1pcs NO5124

Feature:

Very useful silicone socks: will 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.

Made of a heat-resistant, non-stick silicone material our socks will 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.

Helps to keep the hotend temperature extremely stable, particularly if you use high-airflow cooling around the nozzle to cool the print.

Highest safe temperature resistance is about 230 -250 degC/ 446 F-482F

Size: 20 x 20 x 10 mm/ 0.78 x 0.78 x 0.39 inch
