Ultimaker Silicone Nozzle Seal UM3 & F Series
Pack of six silicone nozzle covers.
This is the smaller size (42.5 x 30.75 mm), which is compatible with the UltiMaker 3 and Factor 4.
The nozzle cover is a consumable item; it can wear over time due to the heat from the print cores. Check the nozzle cover quality regularly and replace it when it looks worn, burnt, or damaged.
