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

drop in replacement. no issues. came in silver.

works great

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.

I used to make little rubber parts. These are good quality.

Unlike some of the other Silicone Covers available, these were just like the originals. They fit and work just as good as the original cover that come with the printer.

Fits perfectly but I had to adjust my temp levels because this version sits lower and covers most of the nozzle and since my settings had already been adjusted for heat creep, it’s too low of a temp now. It’s an easy fix and I adjusted the temp a few degrees hotter so keep this in mind if you have your settings set to avoid any heat creep. Otherwise it’s a perfect fit for an Ender 3 Pro.

Other brand smelled horrible when heated and smoked. These are fine.

i ordered this because i did not want rubber around my nozzle. if i wanted a version of the silicone sock that had rubber around the nozzle i would have ordered them, because unlike this listing, they had double the quantity. not happy. not worth going through the process of getting a refund and getting the same item from the same seller under a different name.

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.

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