Good quality, slightly tight
The material feels durable and heat resistant. It was a bit difficult to install initially due to the tight fit, but once on, it stays secure.

Perfect fit for my P1S
This silicone sleeve fits snugly on the hotend. It definitely helps maintain consistent temperatures during long prints and protects against accidental burns.

Durable and effective
Been using this for three months now with daily printing. No signs of wear or degradation. Excellent value for the price.

Does the job but smells at first
It works well for insulation, but there was a strong rubber smell during the first few hours of heating. It went away after a while though.

Improved temperature stability
I noticed less fluctuation in chamber temperature when printing ABS. The insulation works as advertised. Highly recommended for engineering filaments.

Essential safety upgrade
Great addition for anyone with kids or pets around the printer. It covers the hot components effectively without interfering with the fan airflow.
Q: What is the maximum temperature this silicone can withstand?
A: Our high-temperature silicone is rated to withstand continuous exposure up to 300°C (572°F), which covers all standard filament printing temperatures.
Q: Can I leave this on while cleaning the nozzle?
A: Yes, the design allows access to the nozzle tip for cleaning while keeping the upper heating block covered. Just ensure the printer is cooled down before touching.
Q: Is this compatible with the original Bambu Lab X1 Carbon?
A: No, this sleeve is specifically designed for the P1S and P2S series hotends. The X1 Carbon has a different hotend assembly geometry.
Q: Does this interfere with the part cooling fan?
A: Not at all. The sleeve is contoured to fit around the heater block without obstructing the airflow from the part cooling duct.
Q: How do I remove it if I need to replace the hotend?
A: Simply peel it off gently starting from the bottom edge. It is flexible and reusable, so you can transfer it to a new hotend if needed.
