The Holman Low-Density Riser Tube, measuring 4mm x 25m, is the perfect solution for seamlessly connecting your 4mm micro-irrigation system to the main water supply line. Crafted from low-density polyethylene (LDPE), this tube ensures a robust and dependable connection with 4mm threaded fittings, offering a secure grip. It's important to note that this connection specifically requires threading; a 4mm barb is not suitable. Primarily designed for vertical installation along irrigation stakes, the rigid nature of the riser tube plays a crucial role in stabilizing micro-jets or micro sprays.

  • 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 throughout your garden beds
  • The connection between the rigid tube & the 4mm fitting, is the most important
  • The 4mm thread bites into the rigid tube to connect
