The Holman Low-Density Riser Tube, measuring 4mm x 10m, is an essential component for establishing a reliable micro-irrigation system in your garden. Crafted from low-density polyethylene (LDPE), this tube ensures a secure and durable connection to 4mm threaded fittings. The threaded connection is crucial, as a 4mm barb is not compatible; instead, the 4mm thread firmly grips the rigid tube, providing a steadfast link. Designed for vertical installation, the riser tube connects to the main poly pipe water supply line, effortlessly ascending an irrigation stake to support micro-jets or micro sprays.

  • The 4mm thread bites into the rigid tube to connect
  • 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
