<p>With these new heater cartridges, E3D has managed to improve on our already first-class 30-watt heaters. We have also added a connector, so that combined with our thermistor you can now change Hot Ends without having to modify all your cable routing. The cable included is also crimped with ferrules at the other end to make plugging in your new cartridge much easier and neater (see images). Get your HotEnd hot quickly and reliably hit the highest of temperatures with these high shiny new cartridges. Every heater comes with one metre of silicone-insulated high-temperature cabling, and is available in 12V or 24V.</p>
