I installed these on my Ender 3 Pro and they held the teflon tubing well - too well. When I had a clog and had to pull the hose out to free it, I couldn't pull the hose out without cutting it open and replacing the entire coupler. According to reviews, some connectors have a latch that requires you to push forward and then pull back to remove the hose. which you can't do if there's no room to move forward (ie - the tube is in the correct position relative to the nozzle). They are great and last great until you need maintenance that you are stuck.
