So I got the hot end taken apart after it had a melt down and my friend and I noticed something a little strange about the hot end.
First the threads on the brass tube from the heater block were wrapped in Teflon or fiberglass tape, is this normal or a sign of bad machining? The wite on the threads in the second pic is the tape.
There was also abs on the threads but that was from the heater block shearing out the threads from the peek housing.
The ptfe liner is red which I have not seen yet. How common is a red ptfe liner?
When I got the hot end I noticed the heater block had a slight angle to it while screwed In to the peek housing.
