Perfect Fit for Dragon HF
This sleeve fits my Dragon HF hotend perfectly. It slides on easily and provides excellent insulation. My temperature stability has improved noticeably since installing it.

Great Insulation Upgrade
Noticed better temp stability and less heat creep. Essential accessory for anyone running high temperatures. Highly recommend pairing this with a proper fan duct.

Good but Delicate
Works well and keeps the heat in. Just be careful during installation as silicone can tear if you pull too hard on the edges. Otherwise, it does the job.

Fast Delivery and Quality
Arrived quickly and works exactly as described. The silicone quality feels durable and heat resistant. No issues after several weeks of printing.

Essential Upgrade
Honestly, this should come standard with the hotend. It protects your cooling fans from radiant heat and helps maintain consistent nozzle temperatures.
Q: What is the maximum temperature this can withstand?
A: The sleeve is rated for continuous use up to 300°C. It is suitable for most common filament types including PLA, PETG, and ABS.
Q: Does this come with any adhesive to hold it in place?
A: No adhesive is needed or included. The sleeve is designed to fit snugly via friction. Using adhesive may damage the sleeve during removal.
Q: Is installation difficult?
A: No, installation is straightforward. Ensure the hotend is cool, then simply slide the sleeve over the heater block until it sits snugly.
Q: How often should I replace the silicone sleeve?
A: There is no fixed schedule, but we recommend inspecting it regularly. Replace it if you notice tears, significant deformation, or if it becomes brittle over time.
Q: Does this fit the Dragon HF version specifically?
A: Yes, this silicone sleeve is designed to be compatible with the Dragon HF, as well as the standard Dragon, Dragonfly, and Rapido series hotends.
