Coupling pieces / reducing pieces
The use of coupling pieces
Coupling pieces / reducing pieces allow water to be easily transported from a pump to one or more final destinations. Hoses and sprinklers come in different sizes, which may make connecting them a bit more difficult. However, we offer a wide range of coupling pieces that in principle can be used to adapt a pump to any desired situation. Please read below to see which coupling piece is needed for which purpose.
The Gardena-type click coupling connector is a well-known concept in the consumer world. A simple click, click, and you are done; that is how easy it can be. This system is an ideal solution for simple garden irrigation with one or at most two sprinklers.
Please note: We advise you not to connect a Gardena click coupling connector to the outlet of a water pump. Its passage is so narrow that the water pump will be unable to operate at full capacity and release its pressure. As a result, insufficient water and pressure will be left in, for example, your sprinkler. However, a click coupling at the end of a hose - for example, to connect it to a sprinkler - is not a problem. As regards the outlet of the water pump, we advise you to use a hose socket, which will improve the capacity and extend the pump's lifespan.
A quick coupling, also known as GEKA couplings, is just as handy as a Gardena click coupling connector. In this case, you do not click one coupling into the other but screw them together. Quick couplings continue where Gardena's click coupling connectors stop, and they come in a wide range of diameters / screw connections up to 40 mm / 1 ½".
In addition, quick couplings are universal, which means a 40 mm model, for example, can be connected to a 25 mm model.
Please note: We advise you not to use quick couplings for the suction connection of a self-priming pump, such as garden or booster pumps. These couplings tend to let air through during priming, as a result of which the pump will be unable to draw in water adequately. This will have the same effect as if you were to drink a glass of water through a straw that has a hole in it.
A hose socket should always be used together with a hose clamp, it is used for making a hose connectable. The socket - the elongated end part - is slipped into the hose, the hose is then secured with a hose clamp. This end bit is usually a screw coupling or, if it involves a different fitting, a quick coupling, and can be connected to the coupling - for example, the pump outlet - to which you want to attach the hose.
A hose clamp is used to secure a hose in place on a hose socket and can be attached by tightening it with a flat screwdriver.
A reducing bush is used to connect an internal (female) to an external (male) screw coupling when the male coupling is too small compared to the female one. In a reversed situation (the female screw coupling is too small compared to the male one), you should opt for a socket nipple.

Elbow / bend
An elbow / bend is used to create a bend without kinking the hose and/or the pipe. It can also be mounted directly onto a water pump to reposition the inlet or outlet straight from the pump.
A T-connector is used to divide a hose / pipe / exit to two ends from which you can continue coupling.
A plug is used to close off a coupling such as a screw coupling. This usually happens only on a distributor when, for example, you do not want to use all exits.
LDPE pipe connectors
Various couplings are specifically suitable for use with LDPE pipes.
Drip hose couplings
Various couplings are specifically suitable for use with drip hoses.
