Ender 3D Printer Parts Silicone Socks/Aluminum Heater Block/Stainless Steel Throat for MK7 MK8 Extruder Kits Ender 3/Ender 3 Pro/Creality CR-10 /CR10S /S4 /S5 (3 Packs)

Got these for the Ender 3 Pro and they fit perfectly. Had to replace a setup today after some cheap PLA clogged up my whole extruder. These went together with no issues and I havent had any issues with leaking nozzle heads or anything.

If you want to keep taking apart your hot end, this is the product for you. Filament melts and comes out of everywhere except the nozzle. Stay away

Got these to have spares around, since I always end up needing them. And theyve been good to have around. Quality is on par with what you get on the stock hotend. Do note however that they dont come with any of the set screws. But the heatbreak works great with PLA, and heat block is a drop in replacement as well. Good price.

Good product for my ender 3 pro. Had some issues hut the seller was quick to fix them.

Not sure what other negative reviewers are getting, but the ones I received are spot on. These are an exact match to the original, though I do like the gold anodizing on the heater block better than the stock bare aluminum. Im in the middle of a 2 day print with no issues.

this heats up faster than my v2 which use to out-pace my 3 pro will be switching my v2 to one of the extras soon to compare speed buy this product its good

Fit my ender 5 pro with a gulfcoast robotic all metal hotend perfectly. The stock one would not stop leaking no matter what I tried and these new blocks finally fixed that. Quality and finish seem to be better than original so far. Would definitely recommend.

Im using this on my longer lk5 its working

So far so good. Fit my Ender 3v2 perfectly after I damaged my OEM one they came with the printer. Great value and installed in under 5 minutes. Seems to come temp at a quicker rate as well.

Awesome replacement quick install would buy again
