LD Poly Micro of 4mm Riser Tube is ideal for connecting 4mm micro-irrigation from the main supply line. The low-density polyethylene (LDPE) material provides a strong, reliable grip onto 4mm threaded fittings.

Riser tube is predominately used to run from the main poly pipe water supply line, vertically up an irrigation stake to mount either a micro jet or micro spray. The rigid material helps keep these sprays in place. Create a micro-irrigation system to run and throughout your garden beds.

The connection between the rigid tube & the 4mm fitting is most important. This connection must be threaded. The 4mm thread bites into the rigid tube to connect. A 4mm barb can not be used.
