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

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

Not much to say, standard heat sock. Seem to hold up pretty well to wear.

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.

drop in replacement. no issues. came in silver.

works great

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

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.

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.

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