Silicone Hotend Sock for K2 Plus/Hi – 280°C Heat Resistant
Silicone Hotend Protective Sock for K2 Plus / Hi 3D Printers
Keep your 3D printer's hotend running at peak performance with this precision-fit silicone heated block protector sock. Engineered specifically for the K2 Plus and Hi hotend structure, this compact sleeve locks in heat where it matters, shields components from filament residue, and makes daily maintenance a breeze — all without any tools.
Key Features
- Superior High-Temperature Resistance: Made from high-performance silicone, this sock withstands continuous working temperatures up to 280°C without deforming or melting. It reliably insulates the hotend during long print runs and routine maintenance.
- Precision Custom Fit: Exclusively designed for the K2 Plus and Hi hotend structure. The snug snap-on fit prevents loosening or shifting — even during high-speed printing — ensuring stable, uninterrupted performance.
- Excellent Thermal Insulation: High-density silicone minimises unnecessary heat loss from the hotend, maintaining a stable nozzle temperature for consistent layer adhesion and reduced energy consumption over time.
- Durable & Corrosion-Resistant: Reinforced wear-resistant silicone effectively resists residue buildup from PLA, ABS, and other common filaments. Withstands frequent disassembly and friction, extending hotend service life and lowering maintenance costs.
- Tool-Free Installation & Easy Cleaning: Smooth non-stick surface and snap-on design allow installation or removal in seconds. Filament residue wipes off effortlessly, saving you time between print jobs.
