Essential safety upgrade

If you have kids or pets near your printer, this is a must-have. It effectively insulates the heater block. Installation took less than a minute.

Works well

Fits the Neptune 4 Plus without any issues. It's a bit tight at first but stretches to fit snugly. Good purchase overall.

Good protection, slight smell initially

Does exactly what it is supposed to do. There was a slight rubber smell during the first few prints, but it went away quickly. Great value for the price.

Cheap insurance against burns

For such a low cost, this provides great peace of mind. No more scalded knuckles when changing filaments. Would buy again.

Stable temperatures

I noticed my hotend maintains temperature slightly better in my drafty garage since installing this. The silicone quality feels premium.

Perfect fit for my Neptune 4 Max

This sleeve fits perfectly on my hotend. It keeps the heat contained and I no longer worry about accidentally burning my fingers during bed leveling. Highly recommended.

5 FAQ

Q: Does this interfere with the part cooling fan?

A: No, the design includes precise cutouts that ensure full airflow to the cooling fan and heatsink fins.

Q: Can I leave this on while printing ABS at 240C?

A: Yes, the silicone material is rated for temperatures well above 240C, making it safe for ABS, PLA, PETG, and other common filaments.

Q: Is installation difficult?

A: Not at all. Simply slide the sleeve over the nozzle and heater block until it sits flush against the heatsink. No tools are needed.

Q: How do I clean this if it gets dirty?

A: You can wipe it down with a damp cloth once the printer has cooled completely. Do not use harsh chemicals.

Q: Will this fit the original Neptune 4 (non-Plus/Max)?

A: This specific sleeve is designed for the larger heater blocks on the Neptune 4 Plus and Max models. It may be too loose for the standard Neptune 4.
