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.

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!

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.

works great

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.

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.

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

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.
