Creality 3D Printer Parts Upgrade Heater Block Silicone Cover and Brass Nozzle Tips for MK7/MK8/MK9 Extruder Hotend Sock Heat Insulation for CR-10,10S,S4,S5 Anet A8 Ender 3 Pro V2

These fit my Ender 2 Pro just fine. No issues getting them on or off. Great to have a few replacements standing by. I think the original ones have almost a thousand printing hours by the time I replace them and I only replaced because they are so cheap, I figured why not swap em out.

These are nice socks but that are not as pictured. They cover more of the nozzle. Ended up returning them without issue and still looking for what is pictured.

I bought these mainly for the heat socks, I really dont need the nozzles as I already have tons, so I cant speak to them, but the socks are great! And I cant complain about getting some nozzles too, it was a very good price for the package. The socks are exactly what I was expecting. They pop right on, and I havent had one fall off yet, they fit snug. Nothing has caught fire lol, they hold up to the heat well, not much else to say! They are a basic accessory with a simple purpose, theyre doing exactly that, and I have no complaints. Thank you!

It does a fantastic job keeping things cool. I’m able to run PLA parts coolers almost touching the extruder.

These block socks fit better than some others Ive tried. Would buy more again when I need some.

Perfect fit, exact replacement for the factory part on my Ender 3 Pro.

works great

These work well on my Tevo Tornado. These are not supper tight but work. Make sure you put it on so the sock covers part of the Thermister. I was getting thermal limit error messages when I cut the sock to fit around the Thermister. Changed it and my printer works great now.

Replacment rubber covers, not much to say to be honest. They fit my printer fine and work as they are meant to. Good value.

Cheap enough to change when switching my Ender over from long PETg print back to PLA. They work great.
