How do I cut the tube to my required length?

The polyethylene material is durable but manageable. You can easily cut it to your desired size using a sturdy pair of scissors or a sharp utility knife.

Can this tube be buried underground?

Yes. While it is UV-stabilised for above-ground use, it is also designed for underground installation if you prefer a hidden irrigation system.

Is it difficult to bend around corners?

The tube is flexible, but like most polyethylene pipes, it can be rigid when cold. To make it more pliable for tight turns or fitting attachments, try soaking the ends in warm water or leaving the coil in the sun for a few minutes. Alternatively, use an elbow connector such as the Claber 91025.

What size fittings should I use with this tube?

It is a standard 1/2" (13–16mm) main tube. It works perfectly with all Claber Rainjet 1/2" fittings, as well as universal 13mm barbed or compression fittings.

Is it compatible with Hozelock or Gardena systems?

Yes, the 13mm internal diameter is the industry standard for domestic drip irrigation, making it fully compatible with components from Hozelock, Gardena, and other major brands.

What is the maximum water pressure it can handle?

The tube is rated for a maximum working pressure of 4 bar, which is standard for most residential outdoor taps.

Will algae grow inside the tube over time?

No. The tube is specifically designed to be algae-resistant and opaque, preventing sunlight from entering and triggering algae growth that could clog your drippers.

Can I leave it out during the winter?

Yes, the material is resistant to low temperatures and frost. However, it is always recommended to drain the system of water before the first hard freeze to prevent expansion damage to connectors. It is also recommended that both ends of the hose are capped off to avoid creepy crawlies and other unwanted matter from clogging the tube.
