Adjustable 360° Micro Sprinkler / Dripper

This adjustable 360° micro sprinkler provides a simple and effective way to irrigate flower beds, borders, shrubs, vegetable plots and greenhouse plants.

Designed for direct installation into 13mm LDPE supply pipe or for use with 4mm micro irrigation tubing, the removable cap allows the sprinkler to be cleaned easily, helping to maintain reliable performance throughout the growing season.
