Sovol Star-Profile PTFE Bowden Tube — 5m, High‑Temp 260°C for 1.75mm Filament
Product description
Reduced friction by design: the inner channel of this PTFE tubing uses a star-shaped profile to minimize filament contact with the wall. Sovol states this geometry cuts friction by about 30% compared with standard round PTFE tubes, promoting steadier extrusion and improved print fidelity.
High-temperature, durable material: manufactured from high-purity PTFE, the tube withstands temperatures up to 260°C. That heat resistance helps prevent carbonization and brittleness during long, high-temperature or high-speed printing sessions, extending the life of the tubing and maintaining reliable extrusion.
Kit contents and dimensions: you get a 5 meter (16.4 ft) length of white PTFE tubing designed for 1.75 mm filament. The tubing’s typical outer diameter suits 4 mm fittings. The package includes two plastic tube couplers with a 4 mm inner bore for joining segments, plus a PTFE cutter with a sharp razor to ensure flat, square cuts that reduce feeding issues and heat creep.
Performance for fast and flexible printing: the low-friction inner surface (reported coefficient as low as 0.03) helps reduce clogs and makes retractions cleaner, especially when printing TPU or other soft filaments. It’s intended for high-speed setups where consistent filament delivery matters.
Compatibility: the tubing is compatible with many common setups — examples include Bambu Lab AMS and X1/X1C/P1 series, A1 and A1 Mini, Prusa MMU3, and several Creality models such as K1 Max and Ender 3 V3. It’s offered for hobbyists and pros wanting a more robust, higher-temperature Bowden/PTFE feed line.
Pros
- Star-shaped bore reduces filament friction and improves flow
- High-purity PTFE resists heat up to 260°C and avoids carbonization
- Comes with two 4mm couplers and a sharp cutter for neat installations
Cons
- Higher cost than basic round PTFE tubing
- Plastic couplers may not match all OEM fittings exactly
- Requires careful cutting and installation for best results
VerdictThis Sovol star-profile PTFE tube delivers noticeably lower resistance and reliable high-temperature performance for demanding print jobs. The kit gives you 5 meters of tubing designed for 1.75mm filament, two 4mm couplers to join runs or extend length, and a cutter that produces clean, flat ends. It resists carbonization and embrittlement up to 260°C and helps reduce clogs and filament drag—parti

No more clogged tubes
Swapping to this style eliminated frequent filament clogs I had with stock tubing. Higher heat resistance means less expansion and fewer jams, saving time and wasted prints.

Good tube, does the job
Works exactly as expected. Cutter is solid and the extra connectors were handy. Fitment was correct and I’m satisfied with the purchase.

Surprisingly low resistance
I was skeptical but the star profile really cuts resistance. I successfully fed a TPU 90A line through two feet of tubing without problems — something I couldn’t do before. Great for long runs from a dry box or AMS.

Exactly as described
Performs as advertised and met my expectations. Reliable and straightforward.

Best feed upgrade for K1 SE
Swapping to this tubing made filament feed much smoother on my K1 SE. The stock tube allowed the filament to wobble and caused feeding issues; this tube keeps the filament straight and halves the extrusion effort. Flexible and abrasive filaments no longer caused stringing. On K1 SE it fit directly without swapping connectors.

Perfect fit for A1 rearrange
Reoriented my A1 and original cables were too short. This solved the issue with extra length to spare. Cutter made trimming easy. Didn’t need the couplers but they might be useful later.

Useful kit
Simple but practical set — tubing, couplers, and a cutter that actually helps.

Solid build, a bit expensive
Needed longer tubing to reach my filament dryer. The tube is smooth and handled PAHT-CF without snags. Cutter was much better than scissors. Quality is good, but the set feels a bit pricey for just tubing.

Essential and effective
Handy upgrade for any 3D printer. Easy to swap and it performs well.

Looks different than expected
I’ve owned premium tubing before and this unit felt lower quality than what I expected. It worked but didn’t match the look and feel of the previous one I bought.

Un must per le stampanti 3D
Ho sostituito il tubo deformato della mia Ender 2 Pro con questo e la qualità di stampa è migliorata. Il filamento scorre meglio e regge 230°C per molte ore senza problemi. Rapporto qualità buono.

Notable improvement over stock tubing
Both of my printers benefited from swapping to this tubing. The kit included tubing, four connectors, and a sharp cutter. After trimming and installing the tube, flexible filaments printed far better and I could finally print TPU reliably.
