3/8 inch tee (male thread x female thread) with a ball valve and hose outlet is a practical connection for water installations. It allows for the splitting of supply to two outlets and conveniently shuts off the water flow with one motion. Designed for connections in water filtration systems, including refrigerators, under-sink filters, and reverse osmosis systems. Compatible with 1/4 inch hose.
A 3/8 inch tee with valve for refrigerator and filter is a practical water-line fitting that lets you split the water supply into two outlets and, when needed, quickly shut off the flow with a single motion. It is a convenient solution for applications such as a refrigerator with an ice maker, an under-sink water filter, a reverse osmosis filter, reverse osmosis systems, and other water filtration system components. The 3/8" female thread x male thread fitting works with 1/4 inch tubing and is ideal wherever leak-tightness, simple installation, and flexible water treatment at home matter.

This 3/8 inch tee with ball valve is designed for convenient connection of devices that require a stable water supply. It allows you to connect the fitting to the main water line and simultaneously supply two outlets, which makes it much easier to organize installations in the kitchen, under the sink, or in technical systems.
Thanks to the integrated valve, you can easily control the water flow and quickly shut off the supply without interfering with the rest of the installation. This is especially convenient when connecting, servicing, or temporarily disconnecting a device.
The 3/8" water fitting with tee is used in various water installations and filtration systems. It is a versatile component that helps expand or organize the water supply setup without unnecessary installation complexity.
The tee design allows connection to the main water line and simultaneous water supply to two outlets. It is a practical solution wherever one installation needs to serve more than one device.
The applied union nut streamlines installation and later removal of the component. It also helps achieve a secure and leak-tight connection, which is important both during first installation and during service work.
The ball valve allows convenient control of water flow and quick shut-off whenever needed. This feature increases everyday comfort and makes it easier to operate installations working with a refrigerator, water filter, or reverse osmosis system.
This model is designed to work with tubing of the standard 1/4 inch diameter, i.e. about 6.4 mm. As a result, it fits well into popular installations used in household filtration sets, under-sink systems, and solutions such as reverse osmosis systems.
The 3/8" female thread x male thread fitting can be used wherever convenient water splitting and the ability to quickly shut off the supply to a selected outlet are required.
Before installation, make sure that the thread and hose diameters match the system. After connection, check the tightness of all joints and the correct valve position before starting normal operation.
This fitting works well both in simple home installations and in more advanced water treatment systems. It can be a practical supply component for a refrigerator, under-sink filter, reverse osmosis filter, or a complete water filtration system. Its versatile design also makes the product suitable for more specialized configurations, for example in aquarium installations.
If you want convenient branching of the supply and easy flow control, the 3/8 inch tee with ball valve is a functional solution for everyday use.
