What the Capricorn PC4-M10 fitting does

The Official Capricorn Stainless Steel Pneumatic Push-In Fitting PC4-M10 (PC4-01) is a 3D printer part designed to improve the performance and reliability of Bowden extruder systems. The fitting securely connects PTFE tubing to the printer's hotend or extruder, helping maintain consistent filament feeding and reducing the risk of printing issues.

Key features of the stainless steel push-in fitting

• Robust stainless steel construction: The fitting is made from stainless steel for durability and corrosion resistance, outperforming standard brass or plastic alternatives.
• Secure PTFE tube connection: A firm connection between the tubing and the hotend or extruder supports more reliable filament handling during printing.
• Straight-through filament path: The straight-through design allows unobstructed filament passage, helping minimise the risk of clogs and supporting better print quality.

Where to use the PC4-M10 fitting on a Bowden 3D printer

This pneumatic fitting is particularly suitable for the hotend side of Bowden-style 3D printers. A reliable and sturdy connection at this point is essential for stable extrusion and consistent printing results.

Use cases for Creality CR-10 series and similar printers

The Capricorn PC4-M10 fitting is well suited to Bowden-style machines such as the Creality CR-10 series. In these setups, the fitting helps support more consistent and reliable filament extrusion, contributing to improved print quality and overall printer efficiency.
