Does the job well
The insulation properties are excellent. It helps maintain consistent nozzle temperature. The fit is snug, though it took a little effort to slide on initially.

Good value, random color is fine
I received the blue one, which looks great on my printer. It handles the high temperatures without deforming. Only giving 4 stars because I wish I could pick the color.

Essential safety accessory
If you run your extruder at high temps, this is a must-have. It significantly reduces ambient heat around the fan and protects fingers from accidental contact.

Perfect fit for my setup
This silicone sleeve fits my Mosquito hotend perfectly. It keeps the heat contained and prevents accidental burns while tweaking prints. The material feels very durable.

Sturdy and reliable
Been using this for three months now with ABS and Polycarbonate filaments. No signs of melting or degradation. Highly recommended for high-temp printing.

Great protection
Simple product but makes a huge difference in safety. My kids can't accidentally touch the hot block anymore. Very happy with this purchase.
Q: Will this fit a standard V6 hotend?
A: No, this sleeve is specifically designed for Mosquito-style heating blocks and may not fit E3D V6 hotends correctly due to size differences.
Q: Does this come with screws or mounting hardware?
A: No, this package includes only the silicone sleeve. It relies on friction and the existing geometry of your heating block to stay in place, so no additional hardware is needed.
Q: Can I choose the color before ordering?
A: Unfortunately, the color is selected randomly from our stock (Black or Blue), and we cannot accommodate specific color requests for this item.
Q: Is this safe for printing PEEK material?
A: Yes, the sleeve is rated up to 280°C. While PEEK often requires higher nozzle temps, the sleeve provides good insulation for the upper range; however, ensure your specific printing parameters do not exceed the material limits continuously.
Q: How difficult is it to install?
A: Installation is very simple. Just ensure the hotend is cool, then slide the sleeve over the heating block until it sits flush against the thermal break.
