Description
The 3/8'' connection for an osmosis filter with a tee and 1/4'' valve is a practical mounting component for supply installations of an osmotic filter, reverse osmosis system, and other devices connected with a 1/4'' hose (6.4 mm). It allows convenient connection to an existing water installation under a standard wall-mounted tap above the sink or between the valve and the hose supplying water to a washing machine or dishwasher. The built-in 1/4'' valve makes it possible to quickly shut off the water supply, which simplifies installation, servicing, and everyday use of the water filtration system.

Connection for an osmotic filter and other devices supplied with a 1/4'' hose
This compact connection was designed for simple installation in systems where supply via a 1/4'' hose (6.4 mm) is required. It works both as an element for connecting a water filter and as a convenient mounting solution for devices requiring a stable water supply.
Thanks to the tee design, the water supply can be split without the need for complicated modifications to the installation. It is a practical choice for household applications, especially where a reverse osmosis filter or other water treatment solution is installed.
Main applications
- connection of an osmotic filter,
- connection of devices supplied with a 1/4'' hose (6.4 mm),
- connection under a traditional wall-mounted tap above the sink,
- installation between the valve and the hose supplying a washing machine,
- installation between the valve and the hose supplying a dishwasher.
Why this connection is convenient in everyday use
The built-in 1/4'' valve increases control over the installation. It allows convenient shutoff of the water supply to the connected system, which is important during installation, maintenance, cartridge replacement, or temporary shutdown of the device.
This solution simplifies the operation of home installations where reverse osmosis or another water filtration system is used. Instead of interfering with the main installation, you can easily manage the supply to a specific device.
Before installation, make sure that the installation, connection point, and connected hose match the required 3/8'' connection size and 1/4'' hose supply (6.4 mm). After connecting, check the tightness of all connections.
Where the connection can be installed
The connection provides flexibility when organizing a water draw-off point in the kitchen, utility room, or at the device installation site. The option to connect under a standard wall-mounted tap above the sink makes it a convenient solution for installing home water treatment systems.
The product can also be used between the valve and the hose supplying a washing machine or dishwasher, making it easier to supply water to an additional device without the need to expand the installation with a separate connection point.
