Irrigation accessories are the small parts that make all the difference in an automatic watering system. Caps, fittings, elbows, drippers... these components allow you to create a custom irrigation network that delivers water exactly where and when it's needed. Whether you're setting up your first system or perfecting an existing installation, each accessory plays a role in optimizing your plants' watering.
An irrigation system is like a puzzle: every piece must fit perfectly. Poor quality accessories leak, clog, and fail at the wrong time. With reliable components, you can create complex circuits without stress. The BOUCHON CAN 16MM SERIE E, for example, neatly finishes your main lines without risk of leaks. For micro-irrigation, the SPRAYER MINIJET 360° 4MM diffuses water 360° with a consistent flow, perfect for even watering around each plant.
Modularity is the big advantage of these systems. You can start simple with a few drippers and evolve to a sophisticated network. Fittings like the Connecteur X DE 4 MM allow you to create branches to supply multiple zones from a main line. And when you need to bypass an obstacle, the COUDE DE 4MM / L DE 4 MM changes the direction of flow without pressure loss.
Diameter is key. Main pipes are generally 16mm, perfect for supplying multiple zones. 4mm capillaries then run to each plant. This difference in diameter creates optimal pressure: strong in the main circuit, moderate at the drippers. The TUBE DRIP 4-6MM SEMI RIGIDE PRÉDÉCOUPÉ simplifies installation with its pre-drilled perforations every 20cm.
For the type of drippers, it all depends on your needs. Fixed-flow drippers (2L/h or 4L/h) are suitable for plants with similar needs. Adjustable ones allow you to adapt the flow plant by plant. Pressure-compensating drippers maintain a constant flow even with pressure variations – practical on long lines.
Also consider finishing accessories: caps to close lines, filters to prevent clogging, pressure reducers if your network is too powerful. A well-designed system is one that works for months without intervention.
For a classic system, use 16mm for main lines and 4mm for capillaries to each plant. 16mm handles higher pressure and supplies multiple branches without flow loss. 4mm fittings easily connect to the main pipe with special punch tools. This 16mm/4mm combination is the standard that works in 90% of indoor installations.
Start by installing a tap or valve on your reservoir, then connect a standard garden hose to your growing area. At the entrance to the zone, place a pressure reducer (1-2 bars maximum) and a filter to prevent impurities. Then, connect your 16mm main pipe with a suitable connector. If your reservoir is elevated, gravity may suffice; otherwise, a small circulation pump will do the trick.
Fixed-flow drippers always deliver the same volume (2L/h, 4L/h, 8L/h) regardless of pressure – simple and reliable. Adjustable ones allow you to modify the flow from approximately 0 to 70L/h, perfect for adapting watering based on plant size. Pressure-compensating drippers maintain a constant flow even if pressure varies in the network, ideal for long lines where pressure drops at the end of the circuit. For beginners, fixed 4L/h drippers are suitable for most situations.
Use a special punch tool to make clean 4mm holes in your 16mm pipe. Firmly push in the capillary connector – it should make a small "click" when it locks. To secure the main pipe, use fixing clips approximately every 50cm; this prevents it from moving and pulling on connections. Capillaries can be laid on the ground or secured with stakes near each plant. Always test your installation at low pressure before increasing to the final flow rate.
A filter at the head of the network is essential, even with tap water – limescale particles can clog drippers. Choose a filter of at least 120 mesh (125 microns). The pressure reducer prevents drippers from bursting or leaking – set it between 1 and 2 bars maximum. For maintenance, plan for cleaning caps at the end of the line for periodic flushing. A timer with an automatic flushing function is ideal for keeping the system clean effortlessly.

To install a drip irrigation system, I always start by planning the pipe layout and the location of the drippers. Then, you need to connect the main pipe to your water source, and then connect smaller diameter secondary pipes, such as the PRE-CUT SEMI-RIGID DRIP TUBE 4-6MM, using connectors. Finally, I insert the drippers near each plant. It's a very efficient system for saving water.
The choice of fittings primarily depends on the diameter of your pipes and the type of connection you need. For 16mm pipes, a STRAIGHT CONNECTOR 16MM is ideal for extending a line, while a Reduced T-piece - 1/2'' - Male Thread - 16mm will allow you to create a branch. It is crucial to ensure that the fittings are watertight to prevent leaks and pressure loss.
A check valve is an essential component to ensure the proper functioning of your irrigation system. Its role is to prevent water from flowing backward against the current, especially when the pump stops. This prevents the pump from losing prime and protects your system from impurities that could flow back. For small pipes, the CHECK VALVE 4MM is perfect.
The main difference lies in their water diffusion method. The ROTARY SPRAYER WITH VARIABLE FLOW 360°, as its name suggests, rotates to distribute water over a larger area with an adjustable flow, ideal for larger areas or plants requiring uniform humidity. The MINIJET SPRAYER 360° 4MM, on the other hand, delivers a finer, more concentrated jet over 360°, perfect for individual plants or smaller areas requiring targeted watering.
The choice of pipe diameter is crucial for the efficiency of your system. For the main line, I generally use a larger diameter (13 to 20mm) to maintain good pressure. For branches to individual plants, I recommend smaller tubes, such as the PRE-CUT SEMI-RIGID DRIP TUBE 4-6MM. This allows for precise distribution and avoids excessive pressure drops over short distances.
For all your irrigation spare parts, such as Dripper Caps 4mm X 10pcs, CAN CAP 16MM E SERIES or X CONNECTORS 4 MM, I advise you to turn to specialized horticulture or irrigation websites. You will find a wide selection of products adapted to your specific needs and of professional quality, such as on our site, where we offer a complete range of accessories.
