Hose Coupler Set Ø6–28 mm (Same Size)

🔧 Description

Set consisting of 3D printable hose barb pipe-to-pipe fittings, designed to connect pipes of equal diameter with excellent compatibility with standard flexible hoses

The project has been prepared with multi-profile files + separate single models for each diameter (measurements Ø6–Ø28 mm refer to the inner diameter of the pipe to be connected), so you can:

• print all fittings in a single print
• print only what you need
• avoid manual modifications to the plate
• quickly choose the most suitable diameter for your pipe

The package includes the following measurements (inner diameter of the pipe to be connected):

Ø6 mm
Ø8 mm
Ø10 mm
Ø12 mm
Ø14 mm
Ø16 mm
Ø18 mm
Ø20 mm
Ø22 mm
Ø24 mm
Ø26 mm
Ø28 mm

Ideal for:

• water or air pipe connections
• irrigation systems
• workshop and DIY
• tests and prototypes
• quick adaptations on existing systems

✔ Direct pipe-to-pipe connection
✔ Complete set with pipe diameters from Ø6 to Ø28 mm
✔ Multiple files for single or complete printing
✔ Geometry optimized for FDM printing
✔ Simple, compact, and robust structure
✔ Useful for quick connections, tests, and adaptations

The pipe insertion area is designed with spaced hose barb profiles, intended to:

✔ improve grip on the pipe
✔ reduce the risk of slippage under pressure
✔ allow correct tightening of the clamp, which can work between the teeth without deforming the fitting

This geometry ensures a more stable and secure fastening even with soft pipes

⚠️ Print Notes

To ensure reliable printing, the models include supports and small outer brim

✔ The supports are structural and necessary to correctly support the geometry during printing
✔ They are designed to ensure stability and good surface quality in critical areas

✔ Small internal brim are also present, designed to:

• improve bed adhesion
• reduce the risk of detachment during printing
• increase stability, especially in larger diameter parts

👉 After printing, supports and brim must be removed
👉 The supports are optimized for easy removal without compromising the part

After numerous tests, complete removal of the supports did not allow for adequate model quality to be maintained
For this reason, they have been optimized and retained to ensure precision, stability, and a better final result

⚠️ Caution

Not suitable for high pressure, hot water, or critical systems
To improve sealing, the use of PTFE (Teflon) tape is recommended when necessary
