Essential Upgrade
Cheap way to improve print quality. It protects the heater block from accidental burns and stabilizes thermal performance.

Reduced Heat Creep
I noticed less clogging after installing this. It maintains the temperature better than running the block bare. Great value.

Good but tight
The insulation works well, but it was a bit difficult to slide over the heater block initially. Once on, it stays secure.

Smells at first
Works as intended, but there was a strong rubber smell during the first few heats. It went away after a while.

Perfect Fit for V6
This sleeve fits my E3D V6 perfectly. It keeps the heat consistent and helps prevent heat creep. Highly recommended for anyone experiencing clogging issues.
Q: Does this fit MK8 heater blocks?
A: No, this sleeve is specifically designed for E3D V6 and NV6 style heater blocks. It will not fit MK8 geometry.
Q: Will this affect my PID tuning?
A: It may slightly change the thermal dynamics. We recommend running a PID autotune after installation for optimal results.
Q: What is the maximum temperature this can withstand?
A: The silicone material is rated to withstand continuous temperatures up to 300°C (572°F).
Q: Is adhesive needed to keep it in place?
A: No, the silicone friction holds it securely in place without the need for any glue or adhesive.
Q: Do I need to remove the part cooling fan to install?
A: Yes, you typically need to remove the part cooling fan duct temporarily to slide the sleeve over the heater block.
