I have been getting clogs and believe that it may be due to a damaged PTFE tube inside my hot end. I have a replacement (it came with my printer), but I can't seem to fit the tube into the nozzle.

I also tried to turn the original PTFE tube around, and I can't get the other end to fit into the nozzle either.

Is there a trick to it?

In the end, I was able to get the tube in the nozzle.

It took a lot of patience, and it seems to help if the nozzle is warm as well.

What kind of printer do you have? Is it a FlashForge? They sell replacement PTFE tubes on their website, and you can also buy them on Amazon. Just be careful you are buying the correct tube for the correct printer. For example, the Flashforge Finder does not use the same size PTFE tube as the Flashforge Creator Pro or Flashforge Dreamer.

If you had trouble once, you can bet you will probably have trouble again. You should probably buy the part now before you need it. I tell you this as I sit without a working printer (and I have three) while I wait for parts.

Just be sure you buy the correct size tubing.

For the sake of the few pennies, I'd buy the threaded tube with the PTFE already in from any internet auction site.
