Water connection 3/8 inch (male x female) with a built-in ball valve and a 1/4 inch hose inlet. Designed for connections in water installations for under-sink systems, including filters and reverse osmosis kits. Facilitates the connection and quick shut-off of water supply.
The 3/8 inch connection with valve for a reverse osmosis water filter is a practical mounting component for under-sink water installations. The GW x GZ configuration model is equipped with a ball valve and a 1/4 inch hose inlet, making it easy to connect devices such as a water filter, osmosis filter, reverse osmosis system, or other water treatment solutions. This convenient connection not only allows for a neat and functional installation, but also makes it possible to quickly shut off the water supply during service, cartridge replacement, or expansion of the water filtration system.

This component has been designed for convenient integration into an existing water installation. The 3/8 inch water connection with internal and external thread and a 1/4 inch hose branch is especially suitable for under-sink installations, where compact size, simple installation, and the ability to quickly shut off the flow are important.
The integrated ball valve increases everyday user comfort. It allows the water supply to the device to be shut off in a simple way without interfering with the main installation. This is especially useful when connecting devices such as a reverse osmosis filter, a reverse osmosis system, or a classic water filter installed under the countertop.
The 3/8 inch water connection (GW x GZ) with ball valve and 1/4 inch hose inlet is used as a connection in water installations for under-sink systems, including reverse osmosis systems.
It is the right choice wherever a stable and convenient water branch to a filtration device is needed. The component is suitable for domestic water treatment applications and can be used when assembling systems that use 1/4 inch tubing.
Before installation, make sure that the 3/8 inch connection size and the 1/4 inch tubing are compatible with the installation and the connected device. The ball valve allows the water supply to be conveniently shut off during service, maintenance, or replacement of system components.
The connection is intended for installations where water treatment devices are mounted under the sink. Thanks to the 1/4 inch hose branch, it can serve as a functional supply point for solutions used in homes and apartments.
In practice, it is used, among other things, when installing:
The design includes a 3/8 inch connection in a GW x GZ configuration, an integrated ball valve, and a 1/4 inch hose inlet. This combination of elements simplifies installation and reduces the need for additional parts to shut off the flow.
In everyday use, this means greater convenience when operating the installation. If temporary disconnection of the device is needed, for example during maintenance of the reverse osmosis system, the water supply can be shut off without dismantling the entire setup.
