Internal Diameter: 0.16” / 4mm
Outer Diameter: 0.28” / 7mm
The tubing is designed to work with a pressure of between 15 and 45 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.
