3/4 inch connection with a valve for connecting the reverse osmosis filtration system to the home water installation. Fits standard 3/4" valves and 1/4" (6.4 mm) hoses. Allows installation under the faucet in the wall above the sink or connection between the valve and the supply hose of the device, e.g., a dishwasher or washing machine. Provides a tight, hygienic connection and facilitates shutting off the water supply.
The 3/4'' connection with valve for reverse osmosis and wall-mounted faucet is a practical installation component for connecting a reverse osmosis system, an osmosis filter, or another water filtration system to a domestic water supply. It fits standard 3/4" valves and 1/4" (6.4 mm) tubing, making it suitable for installation under a wall-mounted faucet above the sink, as well as between the valve and the supply hose of household appliances. It provides a tight, hygienic connection, easy installation, and convenient shut-off of the water supply.

This connection was designed for convenient integration of the water supply line for a filter into an existing water system in a house or apartment. It makes it easier to connect a reverse osmosis system without the need for complicated plumbing modifications.
This solution works well wherever a stable and leak-tight water intake is needed for a system such as reverse osmosis or another water treatment system. Thanks to the integrated valve, it is also possible to conveniently shut off the water supply to the connected system.
Compatibility with standard sizes – the connection fits standard 3/4 inch valves and 1/4 inch (6.4 mm) tubing, making it compatible with most domestic water installations and osmosis filtration systems.
Versatile use – it can be connected directly under a traditional wall-mounted faucet above the sink, and also installed between the valve and the supply hose of appliances such as a washing machine or dishwasher.
Simple installation – the fitting has been designed so that installation is easy and does not require specialized tools or advanced plumbing knowledge.
Safe and hygienic connection – using this type of connection does not negatively affect water quality and does not introduce additional contaminants into it.
Durability and reliability – the design based on corrosion- and damage-resistant materials supports long-term use in domestic conditions.
The connection is intended for standard 3/4 inch valves and 1/4 inch (6.4 mm) tubing. This size combination makes it easy to adapt the component to most common domestic water systems and installations where a reverse osmosis filter operates.
This is a particularly convenient solution for people who want to easily expand their home water filtration system with an additional connection point without having to replace the entire fitting.
The connection can be used in several practical ways:
to connect directly under a traditional wall-mounted faucet above the sink,
to integrate with an existing water system without the need for complicated plumbing work,
to install between the valve and the supply hose of appliances such as a washing machine or dishwasher.
This use allows filtered water to be supplied also to selected appliances, which can be beneficial, among other things, when water hardness affects their operation or maintenance.
The fitting has been designed for the simplest possible installation. It does not require specialized tools or professional plumbing knowledge, which makes it well suited for self-installation or modification of a home water filtration system.
The integrated valve increases convenience because it allows the water supply to the connected system to be quickly shut off, for example during servicing, replacement of installation components, or temporary shutdown of the filter.
Before installation, make sure that the system uses a 3/4" thread and 1/4" (6.4 mm) tubing. After connecting, check the tightness of all connections before starting normal operation.
Using this type of fitting does not negatively affect water quality. The connection provides a safe and hygienic link that does not introduce additional contaminants into the water.
This is especially important in installations where an osmosis filter or another water treatment system operates, because a properly made connection helps maintain the cleanliness of the entire supply system.
The connection is made of materials resistant to corrosion and damage, which translates into long-term use. This is an important feature in installation components that operate constantly under pressure and must remain leak-tight for a long time.
As a result, the product is a practical solution for everyday household use and makes it easier to effectively integrate the osmosis filtration system with the water installation.
