Hose coupling Brass Gardena 7122-20

The Gardena 7122-20 hose coupling is a brass suction and high-pressure coupling designed for use on pressurised lines up to 40 bar. It connects 32 mm (1 1/4") hoses and features a safety mechanism that prevents unintentional loosening, providing a reliable link between hose sections or to fittings.

Advantages

Constructed from durable brass for corrosion resistance and long service life. The coupling is suitable for both suction and high-pressure hoses, allowing versatile use in garden watering systems. Its safety lock reduces the risk of accidental disconnection under pressure, and the design enables straightforward attachment and detachment for quick hose changes.

Suitable for

• 32 mm (1 1/4") suction hoses
• 32 mm (1 1/4") high-pressure hoses
• Garden watering systems requiring up to 40 bar working pressure
• Connections between hose sections and fittings

Key specifications

How to use

Slide the coupling onto the 32 mm hose end and secure according to the hose and fitting type until the safety mechanism engages. Ensure hose ends are clean and properly inserted to create a tight seal. To disconnect, release the safety feature and pull the coupling off the hose, taking care if the line is pressurised—depressurise first where possible.

Recommendations

Use the coupling only on hoses and systems rated for the specified diameter and up to 40 bar working pressure. Regularly inspect the brass coupling and hose connection for wear, corrosion or damage and replace components if leaks or degradation are detected. Depressurise lines before disconnecting to avoid accidents.
