A good garden hose is only truly effective when its accessories and connectors fit together seamlessly. This guide will show you how to choose the right connectors and create a fully watertight system for your garden.
The basics of an efficient irrigation system
Anyone who starts working in the garden quickly realizes that the "garden hose" itself is only half the battle. The real magic happens at the connections. Whether you want to water a lawn, wash the car, or feed a drip system, the right accessories determine the water pressure and ease of use. A poorly fitting connection not only leads to annoying leaks and wet feet, but also causes a significant loss of pressure, preventing your sprinkler from performing optimally.
Choosing the right diameter is crucial. In the Netherlands, sizes 13mm (1/2 inch) and 19mm (3/4 inch) are standard. For a small urban garden, the lighter 13mm version is often sufficient, but for longer distances or when using powerful pumps, the 19mm version is essential to minimize resistance.
Different types of couplings and their functions
There are countless ways to connect your hose to the tap or accessories. The most common system is the click system, often associated with brands like Gardena. This system uses a male and female push-in connector that locks into place with a simple click.
Tap pieces
Everything starts at the source: the outdoor faucet. A tap connector screws directly onto the thread of your faucet. Pay close attention to the thread size; this is usually G3/4 or G1. Do you have an indoor faucet without a thread? Then special adapters are available that clamp over the faucet nozzle.
Hose connectors and water stops
You attach a hose connector to each end of the hose. However, there's a key difference between a standard hose connector and a water stop. A water stop has an internal valve that immediately shuts off the water supply as soon as you disconnect an accessory (such as a spray head). This prevents you from having to return to the faucet to turn off the water.

Sprinkler heads and showers: The right jet for every plant
Not every plant has the same needs. A powerful jet is ideal for cleaning tiles, but detrimental to young seedlings. Therefore, choosing the right spray nozzle is essential. In "The Best Spray Nozzles for Different Plants," we delve deeper into specific applications, but the basic rules are simple:
- Adjustable Garden Sprayer: Ideal for general use, from a hard jet to a fine mist.
- Irrigation sprinkler: Perfect for borders and potted plants thanks to the soft, wide water jet that doesn't expose the roots.
- Oscillating sprinklers: For evenly watering rectangular lawns without having to be there yourself.
Tips for a 100% waterproof connection
Nothing is as frustrating as a hissing, leaking coupling. Often, the cause is a worn rubber seal or a hose that wasn't cut straight. Use the following steps for a leak-free result:
- Cut the hose straight across: Use a sharp knife or a special hose cutter. A slanted cut will cause the coupling's clamp ring to have uneven grip.
- Check the O-rings: The black or gray rubber rings on the fittings dry out over time. Replace them promptly.
- Use sealing tape: For fixed screw connections, such as a tap connector on a metal pipe, a few turns of Teflon tape can work wonders.
- Tighten the union nut securely: The nut on the hose connector must be tightened firmly so that the 'teeth' of the coupling bite into the hose.

Combining systems
Sometimes you have to deal with different hose diameters in the same garden. Perhaps you have a 19mm main line for pressure, but you want to end up with a handy 13mm hose for manual watering. Reducer couplings and adapters are ideal for this. In " Buying a garden hose: What should you consider regarding diameter and bar? ", we explain how to calculate these transitions without excessive pressure loss.

Maintenance and winterization
Accessories last much longer if you maintain them properly. Limescale is the biggest enemy of sprinkler heads. At the end of the season, soak your sprinklers in a vinegar bath overnight to clear the holes. Frost is also fatal for plastic fittings that still have water in them. "Winterizing Your Garden Hose: Prevent Freezing" explains exactly how to store everything safely.

Frequently asked questions about garden hose accessories
Are all click systems compatible with Gardena?
Yes, most modern brands use the standard universal click connection. This means you can easily click a spray head from another brand onto a Gardena hose connector, provided it's the standard size.
What is the advantage of a brass coupling over plastic?
Brass fittings are much more durable, resistant to UV rays, and can withstand higher pressures. They are less likely to break if accidentally stepped on or bumped against a wall.
How do I prevent my garden hose from coming off the coupling?
This usually happens due to excessive water pressure or the wrong size coupling. Make sure the hose is fully inserted into the fitting before tightening the union nut. For very high pressures, stainless steel hose clamps are recommended over snap-fit couplings.
