Dark blue PTFE Bowden tubing coil, 1 metre length, 6.35 mm outer diameter

CAPRICORN

CAPRICORN PTFE Bowden XS Series Tubing 1m 2.85mm Filament 3.2mm ID

SKU CH-EGJ8-7D6W2

PTFE Bowden tubing with a 3.2 mm inner diameter and friction-reducing additive for smooth feeding of 2.85 mm flexible filaments

  • Reduces filament friction with unique additive treatment
  • Precisely constrains 2.85mm filament via 3.2mm inner diameter
  • Perfectly round bore minimises buckling on flexible 3.00mm materials
  • Pure PTFE construction delivers consistent extrusion performance
  • One metre length suits direct Bowden upgrades

CAPRICORN PTFE Bowden XS Series Tubing

This one-metre length of PTFE tubing is designed for Bowden-style 3D printers that use 2.85 mm filament. Its 3.2 mm inner diameter provides a precise path from the extruder to the hotend. The tubing suits makers who need reliable filament constraint on softer materials. It comes in a dark blue finish.

3.2 mm Inner Diameter Capacity and Headroom

The tight 3.2 mm bore reduces filament buckling and compression inside the guide tube. A unique friction-reducing additive helps softer 3.00 mm filaments slide with less resistance. The consistent roundness maintains steady flow during long prints. It is less suited for rigid filaments that require a looser fit.

6.35 mm Outer Diameter Interface Limits

The 6.35 mm outer diameter fits standard Bowden couplers and fittings used on many desktop printers. One metre of tubing covers typical extruder-to-hotend distances without joins. Builds with longer cable runs will need additional lengths. The pure PTFE construction handles normal hotend temperatures for common filaments.

Questions about this item

Will the 3.2 mm inner diameter constrain 2.85 mm filament tightly enough to stop buckling in my existing Bowden setup?

The 3.2 mm bore leaves only a small clearance around 2.85 mm filament, reducing the space where softer material can compress or kink between the extruder and hotend.

How can I verify the tubing is seated correctly after I install it?

Push the tube fully into the push-fit couplers at both ends; the dark blue PTFE should sit flush with no visible gap, and filament should feed smoothly without catching on a misaligned edge.

Does the 1 metre length include any fittings or cutter, or do I need to source push-fit connectors and a sharp blade separately?

The pack contains only the 1 metre length of 6.35 mm OD tubing; push-fit connectors and a clean cutting tool must be purchased separately.
