Use this barbed joiner to connect 2 micro tube pipes together, or to punch a new micro tube pipe into a 13mm or 19mm poly pipe. We prefer these barbed micro tube fittings over threaded ones, over time we have found them to be less susceptible to blow outs.
These 4mm fittings are designed for use with 4mm Micro Tube, also known as spaghetti tube. They can also be used with Toro's 4mm Drip-Eze drip tube. They are made by Antelco, so you can be sure they will be excellent quality.

Are there any safety standards my irrigation system must meet?
The main safety concern is regarding the water supply. To avoid contamination of the mains water upstream, in most municipalities, a Dual Check Valve is required at the water connection.
Can I have drip tube & sprinklers on the same irrigation zone?
We definitely don’t recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.
Can I mix micro sprays and micro drippers on the same zone?
Due to the different flow rates or each type, it’s often not recommended. A micro spray will typically provide water at 1-2lpm, where as a fixed micro dripper will provide far less, at 2-8lph. However, there are adjustable drippers which can provide higher flows & there are applications where you may want less flow, like pots or native planting.
Can I run an irrigation system off a regular garden tap?
A garden tap is an excellent place to connect your irrigation system. Ideally, install a connection point behind the tap (turn the water off first) so you can still use your tap to fill a bucket when you need to.
Do I need a filter on my irrigation system?
Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find it’s way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.
Do I need a plumber to install or fix my system?
No, unless you’re tapping into your water supply, a plumber isn’t required. Most domestic irrigation systems can be installed by anyone half handy.
How far apart should I position my sprinklers from each other?
Firstly, each sprinkler &/or nozzle has a specified spray radius. Secondly, sprinklers are typically designed to deliver more water at their base & progressively less the further away you get. For this reason, you want to position sprinklers so they spray to hit the base of the next sprinkler. Of course this isn’t possible all the time so in those cases, aim to spray at least 80% of the way. By doing this you will guarantee even water across your lawn or garden.
How many sprinklers can I have on a single irrigation zone?
Each sprinkler & nozzle sprays water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.
I have pot plants on a deck, how do I water them?
You can simply use Micro Drippers or Micro Drip Tube, but your challenge is delivering the water to the pot. We suggest you run Poly Pipe as close as you can & then thin Micro Tube as hidden from view as possible up into the pot.
I want to design & install an irrigation system. Where do I start?
Well you’re in the right place! We’ve got it all here. The first step, is drawing out a plan of your garden, to scale of course. We’ve got Grid Paper in our Product Guides & all the advice you’ll need in there too!
My micro sprays sometimes block up, what can I do?
Because of their small outlets, micro sprays can block from time to time. Fixing individual sprays can be as simple as unscrewing them & simply blowing the blockage back out. To avoid repeat blockages we recommend installing a simple inline filter.
Should I flush my watering system before running it?
As you install a system, it’s almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & you’re good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).
What is the maximum number of micro sprays or drippers on a single irrigation zone?
Each spray & dripper provides water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.
What’s the best type of sprinkler for my garden?
There’s no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.
