This silicone sock from Phaetus makes it possible to keep a more stable temperature in the hot end. With the use of fans to cool certain components in the hotend, the heating block may also be cooled. So to avoid high temperature loss, this sock is a perfect choice.
The properties of silicone prevent melted filaments from sticking to the hotend and thus keep it in its original state for a long time. Both reasons make the purchase of this silicone sock perfect as a replacement or addition to your hotend if it was delivered without it.
