What Capricorn XS Series Bowden tubing does

Capricorn Premium PTFE Bowden Tubing XS Series for 2.85mm is a Bowden tube made from Polytetrafluoroethylene (PTFE) to provide smoother filament feeding, reduced extrusion resistance, and more controlled filament movement in 3D printing systems that use 2.85mm filament.

The PTFE construction brings the non-stick qualities of the material together with the performance characteristics that make the Capricorn Premium XS Series tubing a practical choice for Bowden-based extrusion setups.

Key features of Capricorn PTFE Bowden tubing

Low-friction filament travel

This 2.85mm Bowden tubing delivers a very low coefficient of friction, which helps filament move through the tube without losing the force needed for extrusion. Lower drag through the filament path can also help enhance print speed.

Flexible PTFE construction with chemical resistance

The tubing retains the flexibility of PTFE, which helps reduce wear and tear during use. Capricorn Bowden tubing is also highly chemical resistant and is described as not reacting negatively with any type of filament.

Designed to reduce extrusion-related feeding problems

Pressure from an extrusion system can sometimes bend filament before it exits the hot end. Capricorn Bowden tubing is machined to have a tight internal diameter, which drastically reduces the filament's bending during extrusion.

Important XS Series tubing features

• Perfectly roundness across the tubing's length for more consistent filament guidance
• Treated with a friction-reducing additive to support smoother feeding performance
• Supports soft filament for broader material handling in suitable Bowden setups

Where this 2.85mm Bowden tube is useful

For resolving common Bowden extrusion issues

This XS Series tubing is suited to users dealing with feeding resistance, lost extrusion force, or filament bending inside the tube. The combination of PTFE flexibility, low friction, and a tight internal diameter is intended to improve filament control through the extrusion path.

For 2.85mm filament printing setups

The tubing is designed specifically for 2.85mm filament sizes, making it appropriate for compatible 3D printers and extrusion systems that require a Bowden tube matched to that filament diameter.

For printing with materials that benefit from smoother feeding

The friction-reducing properties and support for soft filament make the Capricorn XS Series tubing relevant for users who want more stable movement through the Bowden path, especially where reduced drag and reduced bending can improve extrusion consistency.
