PTFE Tube for 1.75mm Filament with 2 mm inner diameter and 4 mm outer diameter, suitable for compatible direct-drive and Bowden-style extrusion systems.
$0.01 per mm
100,000.00 mm in stock
The PTFE tube 1.75mm filament is opaque white tubing designed to guide filament through compatible direct-drive and Bowden-style extrusion systems. With a 2 mm inner diameter and 4 mm outer diameter, this tubing is commonly used as a filament path liner, replacement Bowden tube, or general filament guide in compatible 1.75 mm filament setups.
This PTFE tube is intended for systems using 1.75 mm filament. The 2 mm inner diameter provides clearance for filament movement, while the 4 mm outer diameter fits many common Bowden couplers, hotend fittings, and extrusion assemblies designed for this tubing size.
PTFE tubing is commonly used because it provides a low-friction path for filament movement. A clean, properly cut PTFE tube can help support smoother feeding through compatible extruders, hotends, enclosures, and filament routing setups.
The current product page lists heat resistance up to 260°C, along with corrosion resistance and UV resistance. These properties make PTFE tubing useful for filament handling, equipment routing, replacement tubing, and other compatible hobby or hardware applications where the tubing specifications match the project requirements.
This PTFE tube is sold by the millimeter, with a 100 mm minimum order. Order the length needed for your repair, replacement, custom filament path, or equipment setup.
