3-Pack 3D Printer Silicone Sock Protective Cover Compatible with Phaetus Dragon Hotend Extruder Heater Block (Silicone Socks)

The heat block I received was a drop in replacement for the original. Threads for the nozzle were a hair tighter than I would have liked but nozzles go in an come out without any trouble.

I ripped the one that came with my Dragon SF in half accidentally, so needed a replacement. These fit perfectly, and are identical with what I had (except, of course, for the "ripped in half" thing). I fully recommend these for my fellow Dragon users.

I purchased this to replace the HF version. Since adding this to my Phaetus Dragon how end, I have not had any clogs.Great workmanship and quality.

The media could not be loaded. Fits well and it insulates about as well as the factory one but mine started smoking the first time I heated it up. It doesnt smoke anymore so I'm assuming it was leftover oil from the factory. In the future, I'll just slowly bring them up to temp and not burn the oil all at once at 320c 🤣

Identical to my original sock. I'm pretty sure they are the same socks, just from a different seller.

Worked for me as a replacement to the one that came from the factory

I’m using this with an original phaetus dragon hf without issue.

No screws, no pins.Maybe not a big deal if you don't go caveman on removing your old block.Pretty big deal if you have an accident
