Heater Cartridge compatible with the MTW Mercury, most E3D and J-Head style hotends. Some nozzles may need the heater hole drilled out very slightly (you can use a C size drill bit available in the US at most Fastenal stores among other places).
- Detachable 1M leads
- 6mm x 20mm
Please note that heater cartridges get very hot, very fast. They can easily heat up to temperatures that will melt the plastic in your hot end. USE THESE AT YOUR OWN RISK.
