Phaetus Rapido 2 High Temp Silicone Sock HF
$5.99
1
Replacement high-temp silicone sock for the Phaetus Rapido 2 HF hotend. This black silicone cover wraps the Rapido 2 HF heater block/nozzle area to reduce plastic buildup and help keep the hotend thermally stable under part-cooling airflow.
Why use the fitted Rapido 2 HF sock?
- Cleaner hotend: the non-stick silicone surface helps keep molten filament from baking onto the heater block.
- More stable heat: the sock insulates the hot zone so fan wash has less effect on nozzle temperature.
- Correct Rapido 2 HF fit: this is the HF-size sock; Rapido 2 HF and UHF socks are different.
