Is that the stock hotend? If so. The PTFE tube goes all yhe way down the the nozzle. If the tube is not sealed to nozzle it can cause clogs to happen. Its honestly a garbage setup for a hotend. There is replacements that are much better. Something like this would be a drop in replacement without any modification to mounts and fan setups. https://a.co/d/0cHOa9nG
