Description
The 3/8" connector with 1/4T shut-off valve is a practical component for water supply installations, designed for water filters and refrigerators. It makes it easy to quickly shut off the flow during service, filter cartridge replacement, or maintenance work. Thanks to compatibility with a 1/4" hose (6.4 mm) and quick connectors on both sides, it works well in installations such as a water filter, water filtration system, osmotic filter, or reverse osmosis system.

Applications and key benefits
This connector with a shut-off valve has been designed as a convenient solution for controlling water supply in home systems powering filtration devices and refrigerators. It allows you to quickly shut off the water without interfering with the main installation, which significantly simplifies everyday use and servicing.
The product is primarily used in water supply installations for:
- water filters,
- refrigerators.
This is a particularly useful component in places where easy service access and the ability to quickly stop the flow are important. The connector can be used, among others, in water treatment systems, refrigerator connections with a dispenser, and in solutions based on reverse osmosis filters.
Construction and operation
The connector is equipped with a shut-off valve whose main function is to quickly cut off the water supply to the filter or refrigerator. This solution increases user convenience and reduces the scope of work during component replacement or periodic system maintenance.
The valve design includes quick connectors on both ends for a 1/4" hose (6.4 mm). This design makes it easier to connect the line and keeps the installation tidy, which is important both in simple systems and in more advanced solutions, such as reverse osmosis or reverse osmosis systems.
