Replacement high-temperature silicone sock for original Phaetus Rapido HF and UHF hotends. Choose the HF or UHF variant to match your Rapido 1 heatblock; the sock insulates the heater block, helps keep melted filament off the metal, and steadies temperature when part cooling is blowing across the nozzle.

Why use a Rapido sock?

  • Keeps the heatblock cleaner: non-stick silicone helps reduce burnt or blackened plastic buildup around the block and nozzle area.
  • Improves thermal stability: the sock keeps heat in the hotend instead of letting part-cooling airflow pull it away from the block.
  • Reduces heat radiating into the print: useful for overhangs, bridges, and sticky materials such as co-polyesters or filled composites.
