PTFE Bowden Tube Kit 2m with PC4-M6 & PC4-M10 Fittings and Cutter — 1.75mm

Product description

This pack contains two PTFE Bowden tubes (2 × 1 meter) cut to length for straightforward installation, plus a handheld cutter and a set of pneumatic fittings and clips. The tubes are fabricated from high-temperature PTFE with a smooth bore and consistent outer profile to ensure steady filament travel and reduced binding.

Each tube has an inner diameter of approximately 2.0 mm to suit 1.75 mm filament and an outer diameter of about 4.0 mm. The tubing is rated to tolerate elevated printing temperatures, making it suitable for common engineering materials such as ABS, Nylon and polycarbonate when used within a compatible hot end assembly.

Hardware in the kit includes four PC4-M6 fittings intended for the extruder side and four PC4-M10 couplers for the hot end. The fittings are brass/copper constructions with a plated finish for wear resistance; they feature a 4 mm passage that mates with the tube’s outer diameter and allow a run‑through trim for neat tube seating.

A dedicated cutter is supplied to create square, burr-free tube ends that help prevent heat creep and feeding issues during retraction cycles. Each pneumatic connector is accompanied by a locking clip to secure the tube against accidental release.

Compatibility is broad for Creality-style machines and other Bowden setups that use 1.75 mm filament: Ender-3, Ender-3 V2, Ender-3 Pro, Ender-3 S1, Ender-5, CR-10 and many similar printers. The kit contains everything required to replace the PTFE path and associated couplers in a typical Bowden extruder configuration.

Pros

  • High-temperature PTFE with smooth bore
  • Includes fittings, clips and a cutter
  • Sized for 1.75 mm filament and common Bowden printers

Cons

  • Tube consistency can vary between batches
  • Some users report occasional fitting breakage
  • Not the top choice for demanding TPU use

VerdictThis kit supplies the core consumables needed to rebuild or upgrade a Bowden filament path: two high-temp PTFE tubes, multiple PC4 pneumatic connectors, clips and a cutter. The tubing’s precise internal diameter and smooth finish make filament feeding steadier and reduce friction for materials such as PLA, PETG and many higher-temp filaments. The copper-plated PC4-M6 and PC4-M10 fittings are servi

Reviews

  1. Casey Lee Bradbury 5/5

    All-in-one replacement pack

    Contained every component I needed to swap the PTFE path on my Ender-3.

  2. Mr. Pj Elliott 5/5

    Does the job

    Simple, functional and gets the filament path back in order.

  3. Chris Hites 5/5

    Would purchase again

    Served its purpose and performed reliably in my setup.

  4. Debra Jones 4/5

    Good connectors, average tube

    The brass-style fittings are solid, but the PTFE quality felt just average — I wouldn’t rely on it for very soft TPUs.

  5. Luis Flores 5/5

    Performs as expected

    Cuts cleanly and integrated into my upgrade without fuss.

  6. Landman 5/5

    Good value, arrived quickly

    A well-rounded set that included the parts I needed to finish the install without hunting for extras.

  7. Joindy 5/5

    Handy maintenance bundle

    Good selection for upkeep and modest upgrades on Bowden printers. The slimmer PTFE fits filament snugly and handled TPU and PETG in my tests.

  8. Carl 3/5

    Looks fine, fittings disappointing

    Everything appears well made except the couplers — I prefer the original fittings installed on my printer.

  9. iain t 5/5

    Neat package, effective cutter

    Items arrived tidy in a box. The cutter made surprisingly clean, square cuts despite its modest look.

  10. Digger 1/5

    Connector failed during use

    A metal fitting fractured inside the feeder and I had to order a replacement, which was frustrating.

  11. Farb 5/5

    Replaceable consumables to try first

    On my Ender-3 I swap everything from this kit when prints start failing. I do the change with the hot end warm, pull the old tube, feed a spare through the heater block, refit the nozzle and secure the fittings.

  12. Milosz Kwiatkowski 5/5

    Exactly what I needed

    Provided the right fittings and tubing for my replacement job.
