Metal ball valve for connecting water supply to filters. Used with a water connection of the appropriate diameter, it creates a tee that facilitates integration into the installation. Fits connections with a mounting hole of 1/4 inch. Outer thread 1/4 inch. The hose connection is made by sliding it onto the spigot and tightening with the nut from the set. The threaded connection should be sealed with, for example, Teflon tape.
Tank valve 1/4T x 1/4GZ is a metal ball valve for connecting the water supply in filtration systems. It works well as a mounting component in solutions such as a water filter, reverse osmosis filter, reverse osmosis system, or other systems designed for water treatment. Combined with the proper water connector, it creates a practical tee that makes it easy and convenient to connect the filter to most water installations.
The model fits connectors equipped with a 1/4-inch mounting hole, has a 1/4-inch external thread, and allows a hose to be connected by sliding it onto the spigot and tightening it with the nut included in the set. It is a durable and functional solution for water filtration systems that require reliable shut-off or water supply.

The metal 1/4T x 1/4GZ ball valve is designed for connecting the water supply to a filter. It is most often used in installations where convenient connection of the filtration system to an existing water network is required.
It is a practical mounting component used both in home filtration systems and in popular solutions such as reverse osmosis, an osmosis filter, or a classic under-sink water filtration system.
The valve is typically used together with a water connector of the appropriate diameter. Once these elements are connected, a tee is created that enables connection to most water installations. As a result, installing a water filter becomes simpler and more organized.
The product fits water connectors from various manufacturers, provided they use a 1/4-inch mounting hole. This is an important practical feature because it makes the component easier to match with many popular filtration sets.
The valve has a 1/4-inch external thread, which is approximately 11 mm. On the hose side, there is a mushroom-type spigot onto which the hose should be pushed. The whole connection is then tightened with the nut included in the set.
This installation method is simple and also convenient in everyday use. It works well in systems where quick connection of the line supplying water to the filter matters.
Important installation notes: the hose connection to the valve does not require additional sealing. The threaded connection between the valve and the water connector does require sealing — for example, PTFE tape can be used. Before installation, it is worth making sure that the connector has a 1/4-inch mounting hole and is compatible with the planned installation configuration.
In systems such as a reverse osmosis filter or another water filter, not only the performance of the filter cartridges matters, but also the quality of the connection components. A solid metal valve helps create a stable connection to the installation while also allowing convenient organization of the water supply to the filtration system.
Thanks to the standard 1/4-inch size, the product fits well into popular solutions used in home water treatment systems. It is a useful component for people assembling a new set or replacing a worn part in an existing installation.
