Reliable replacement part

My old heater broke, and this was an exact replacement. Installation was straightforward, and it's been working flawlessly for two weeks now.

Excellent thermal performance

Very impressed with how evenly this distributes heat. No cold spots in my nozzle assembly. Highly recommend for DIY hotend projects.

Solid industrial grade component

Using this in a custom extruder design. The tolerance is tight, and the stainless steel housing feels durable. Will buy again.

Perfect fit for my Ender 3 upgrade

This heating rod fits perfectly into my custom hotend setup. It heats up quickly and maintains temperature very consistently. Great value for the price.

Works well but instructions needed

The product works great, but as a beginner, I wished there were some basic wiring diagrams included. Had to look up guidance online.

5 FAQ

Q: What is the resistance of this heating rod?

A: Based on the 12V and 40W rating, the resistance is approximately 3.6 Ohms (calculated using R = V²/P).

Q: Does it come with thermal paste or screws?

A: The package includes only the heating rod itself. Thermal paste and mounting hardware must be purchased separately.

Q: How long is the wire lead?

A: The wire leads are approximately 50cm long, which is sufficient for most standard 3D printer hotend configurations.

Q: Can this be used for melting plastic other than PLA?

A: Yes, as long as your temperature controller can manage the heat output, this rod can reach temperatures suitable for ABS, PETG, and other common filaments.

Q: Is this compatible with 24V systems?

A: No, this specific model is designed strictly for 12V systems. Using it with 24V may damage the component. We do offer a 24V version in our store.
