Pressure-compensated dripper

One-Drop, Soaplast’s pressure-compensated and non-inspectable emitter, represents the latest evolution in the field of on-line drippers. Also available in an no-drain version, easy to install and with excellent performance, it is suitable for a wide variety of applications, from domestic gardens to precision agriculture. Also ideal for intensive horticulture, greenhouses and soilless applications.


  • greenhouses
  • nurseries
  • orchards
  • uneven terrain
  • landscaping
  • gardening
  • hydroponics
  • soilless cultivation
  • pulse irrigation

One-Drop® has a compact shape and measures 28mm. Made up of three components, it is produced through an advanced ultrasonic welding process:

1. The base whose color varies depending on the version, draining or no-drain.

2. The silicone membrane that allows the delivery of precise and equal quantities of water over a wide pressure range.

3. The exit consists of a cylindrical labyrinth with large passages and a self-cleaning mechanism, in distinct colors depending on the flow rate.

Pressure-compensated no-drain dripper

Designed for advanced pulse irrigation systems where precise opening and closing pressures are required. The tube does not empty at the end of the irrigation cycle and ensures immediate and uniform irrigation, with significant energy savings.
