Bradas Hose Coupling Stop System 3/4" WHITE LINE WL-2150

Product detailed description

This coupling is commonly used in residential and commercial garden irrigation systems. It is installed by technicians and contractors to connect flexible hoses to water supply points or to accessories such as nozzles, sprinklers, or filters. The coupling is designed for use in low-pressure systems and is compatible with standard garden hose fittings. It is suitable for both new installations and system repairs where a secure and leak-free connection is required.

The coupling is made of durable plastic and features a non-return valve that prevents backflow when the hose is disconnected. This helps to reduce water wastage and ensures that the system remains dry when not in use. It is particularly useful in systems where frequent disconnection and reconnection of the hose is necessary.

Technical parameters

Installation and connection

To install the coupling, first ensure that the hose is clean and free of debris. The coupling is pushed onto the hose until it is fully seated. The connection is secured by tightening the coupling nut by hand or using a wrench. It is important to check that the coupling is aligned with the hose and that there is no twisting or bending that could affect the seal.

Common installation mistakes include using excessive force when tightening the coupling, which can damage the plastic housing, and failing to ensure that the hose is fully inserted into the coupling. It is also important to verify that the non-return valve is functioning correctly by testing the connection for leaks and backflow after installation.

Compatibility and accessories

This coupling is compatible with standard 3/4 inch garden hoses and accessories that use the same thread type. It is often used in conjunction with hose nozzles, filters, and sprinkler systems. When installing, ensure that all connected components are also rated for the same pressure and flow conditions. No additional accessories are required for basic installation, but it is recommended to have a wrench on hand for tightening the coupling nut.

Technical background for designers

The coupling operates by forming a tight seal between the hose and the fitting when the coupling nut is tightened. The integrated non-return valve is a spring-loaded mechanism that closes automatically when the hose is disconnected. The plastic construction provides resistance to corrosion and UV exposure, making it suitable for outdoor use. The coupling is designed to maintain a consistent flow rate and pressure within the system, and its performance is affected by the quality of the hose and the integrity of the connection.

Service and operation

Regular inspection of the coupling is recommended to ensure that the seal and non-return valve remain intact. If the coupling shows signs of wear, such as cracks or leaks, it should be replaced. There are no scheduled service intervals for this coupling, but it should be checked during routine system maintenance. To test the non-return valve, disconnect the hose and observe whether water flows back into the hose. If it does, the valve may need to be cleaned or replaced.

Frequently asked questions

Can the coupling be used with metal hose fittings?
Yes, provided that the metal fittings have a standard 3/4 inch thread that is compatible with the coupling.

Does the non-return valve require maintenance?
The valve is self-cleaning in most cases, but if it becomes clogged with debris, it can be disassembled for cleaning according to the manufacturer’s instructions.

Is the coupling suitable for high-pressure systems?
It is designed for standard garden hose pressure levels. For high-pressure applications, a coupling with a higher pressure rating should be used.

Can the coupling be used in cold weather conditions?
Yes, the plastic material is resistant to low temperatures and will not crack in typical cold weather conditions.
