Essential for high-temp materials

If you are printing polycarbonate or nylon, this is a must-have. My heater cartridge cycles much less frequently now.

Good insulation, slight odor initially

Works great for keeping heat in the block. There was a slight rubber smell during the first few prints, but it went away quickly.

Does the job well

Easy to install and removes the need for excessive part cooling fan speed near the hotend. Recommended.

Great upgrade

Simple accessory that makes a noticeable difference in print consistency. Fits the PT100 version perfectly.

Durable and effective

I've been using this for three months without any signs of degradation. The silicone quality seems very high.

Perfect fit for my V6 setup

This silicone sock fits snugly on my E3D V6 hotend with the PT100 sensor. It has significantly improved my temperature stability when printing ABS.

5 FAQ

Q: Will this fit a standard J-head hotend?

A: No, this specific model is designed exclusively for the E3D V6 hotend configuration with a PT100 temperature sensor.

Q: Is this resistant to melting if the heater goes runaway?

A: The silicone is rated for high temperatures, but thermal runaway is a dangerous fault. Always ensure your firmware thermal protection settings are correctly configured.

Q: Does this interfere with the thermistor reading?

A: Not at all. The sock is designed to insulate the heating block without covering or obstructing the PT100 sensor port.

Q: Can I use this with PLA printing?

A: Yes, you can use it with PLA, though the benefits are more pronounced when printing high-temperature materials like ABS or Nylon.

Q: How do I clean the silicone sock if it gets dirty?

A: You can gently wipe it with a damp cloth once the hotend has completely cooled down. Avoid using harsh chemicals.
