CCTREE 3D Printer Hotend Silicone Sock Heater Block Silicone Cover for Creality Ender Series, CR Series, Anet A8, MK7/8/9 Hotend, Brown,3 Pcs

My insulation on the hotend came off and needed a replacement. These were the perfect replacement. Very happy with this order.

Fit perfect an does what its supposed to

You do not know what you are missing until you try them. Im impressed. My hot-end is clean, no smell and filament does not stick to it. By by kapton tape and insulation.

Works ok not a perfect fit though

Works fine. No issues.

I should have checked first. My Ender 3 Pro came equipped with a silicone sock just like these only black. If you dont have one, these fit perfect (I tried to make sure). One should last a lifetime of printing, but just in case, I now have 3 lifetimes of these available in a drawer.

they fit perfectly and I now have some spares.

Fits perfectly in my ender 3 pro. Would recommend this product to any one how has ender 3 it is easy to install, works great, and keeps the heat were it need to be.

An excellent product if you need to replace your insulation quickly. However, the sock only mostly fits the stock hotends listed, even with the stock insulation removed. is servicable and worth the price for ease of install.

Allows for steady nozzle temperatures.
