PC4-M6 Drying Oven Feed Connector for 3D Printer

### Low Friction Through Hole Design
Unlike standard pneumatic fittings, this PC4-M6 connector allows the 4mm PTFE tube to pass completely through. This creates a continuous, friction-free path for the filament, eliminating scraping and significantly reducing feeding resistance.

### Maintains Dry Box Airtight Seal
Establishes a sealed channel from your dry storage box directly to the extruder . Designed to maintain a low-humidity environment, protecting moisture-sensitive filaments like nylon and PETG from degradation.

### Ideal for Multi-Color MMU Setups
The 4-piece configuration is perfect for building a 4-way filament routing path for systems like Bambu Lab AMS or FYSETC BMCU multi-color feeders . Versatile enough for any DIY dry box or multi-filament project.

### Includes Protective Sealing Caps
When the PTFE tube is detached, cap the fitting to block ambient moisture from entering the dry box . Keeps your stored filaments bone-dry between uses, a feature not found on standard fittings.

### Quick Push-to-Connect Installation
Tool-free installation.Insert the 4mm PTFE tube to lock it securely, and press the release collar to remove it easily . Saves time during setup and filament changes.
