Installation Steps

Technical Information

Internal Diameter: 0.32” / 8mm
Outer Diameter: 0.40” / 11mm

The tubing is designed to work with a pressure of between 15 and 45 PSI.

Burst pressure: 160 PSI

Maximum water volume delivered:

80 Gallons/hour at 45 PSI
70 Gallons/hour at 35 PSI
60 Gallons/hour at 20 PSI

How to correctly attach the tubing to a barbed coupling or drip emitter:

Please make sure you have some form of filtration and pressure regulation installed on your water source.

Why is it important:

Filtration: the couplings and emitters have small openings that can clog with debris or sediments if there’s no filtration used.

Pressure regulation: pressure over 45 PSI can blow off the fittings and damage the micro irrigation system over time. You can find a wide variety of inexpensive pressure regulators on Amazon.com or at your local home improvement store.

Start your installation by leaving your distribution tubing in the sun for about 30

minutes. The sun will soften it, making it much easier to work with. While the line is warming, read through this entire installation section.

Do not use oil or other lubricants to assemble the parts; it will deteriorate the line and fittings and make them easier to blow off under the water pressure.

Do not use glue as it might clog the installation and you won’t be able to clean it in case of debris or sediments.

Step 1 - Soften the tube

Leave your distribution tubing in the sun for about 30 minutes. The sun will soften it, making it much easier to work with it. While the line is warming, read through this entire installation section.

Step 2 - Running the needed length

Run the needed length of 5/16" distribution tube from the water source to your designated area (try not use more than 5 feet of tubing per branch).

Step 3 - Connecting the ends of the Tube

Connect one end of the 5/16" tube to the barbed coupling and the other to an emitter. Make sure the tube covers the barb entirely so it won’t come out when you turn on the water.

Obs: The barbs are designed to be slightly larger than the 1/4" tubing to prevent it from sliding back off. If you find it too difficult to push the tube all the way through, soften the tube end by slightly heating it with a heat gun or soak it in hot water. The tubing will slide on very easily and contract over the barb when cools down, sealing the connection.

Step 4 - Open the water source to flush out any debris

Before closing the circuit, flush out any debris or dirt that may have gotten into the line during installation. Continue flushing until water runs clear.

Step 5 - Closing the circuit

Close the circuit and open the water.

Step 6 - Inspecting the circuit

Inspect the entire circuit and make sure there are no leaks or tube kinks.

Frequently Asked Quaestion Drip Irrigation Emitters

What to do in Winter time?

If you live in an area that has freezing temperatures and/or hard frosts, it will be necessary to completely drain your drip system to prevent the lines and other parts that contain water from being damaged. Please thoroughly double-check the 5/16" tubing as kirks can prevent water from draining.

The 1/4" tubing is being blown off the couplings or the emitters.

This could be caused by the tubing not being fully pushed over the barb or excessive pressure. Reconnect the tube, making sure it covers well the entire barb, and check the pressure. The system should not have an operating pressure higher than 40 PSI. Additionally, you can try cutting the small section of the tube where the barb was initially connected and reconnect.
