Connections 4mm

The 4mm connectors for terrarium rainwater system are essential parts for assembling, extending or repairing a spraying circuit when you want to feed multiple lines with a single pump. With these 4mm rain system connection parts you can design a neat, efficient and easy-to-maintain watering system, adapting the tube path to the shape of the terrarium and to the areas where you need more humidity.

In a well-planned rainfall system, connectors are as important as the pump and nozzles: they allow you to make clean turns, divide the flow to different terrariums or sectors, and keep the tubing fixed without pressure-reducing kinks. If you have a tropical terrarium, a paludarium or several enclosures connected to the same pump, these parts help you create a stable and professional circuit.

✅ Size 4mm: for organizing lines with a single pump.

These parts are designed for piping of 4mm, The watering systems are very common in compact irrigation and nebulization installations. They are ideal for:

• distribute the water to several nozzles

• connect several terrariums to the same line

• redoing worn or leaking sections

• improve the order of the circuit and facilitate maintenance

👉 You can complete the assembly with nozzles, pumps and spare parts from https://www.kanakydesign.com/.

🧩 4 models available (choose the one you need)

Depending on the design of your circuit, you have four formats:

🔹 Elbow connector (L)

Perfect for 90º turns in corners or changes of direction without forcing the tube. Reduces kinks and helps maintain good pressure.

🔹 T-connector

For divide a line in two, creating branches to different areas or nozzles while maintaining a clean layout.

🔹 Y-connector

A very useful alternative when you want a “softer” bifurcation with a more progressive flow in two directions.

🔹 Straight connector

For join two lengths of 4mm pipe or lengthen a line quickly and safely.

💡 Tips for a more stable rain system.

• Plan the route before cutting the pipe: fewer joints = fewer leak points.

• Avoid sharp bends with the pipe; use elbows L for clean turns.

• If you notice low pressure, check for clogged nozzles and minimize unnecessary bypasses.

• In large installations, it distributes nozzles by lines to balance flow.
