Screw (Worm Gear) clamp Gardena 7194-20

The Gardena 7194-20 screw (worm gear) clamp is a steel fastening device designed to secure hoses and pipes with a diameter of approximately 5 cm. Its simple mechanical design provides an adjustable, tight connection to prevent leaks at hose joins and fittings commonly used in garden watering systems. The clamp is intended for repeated use and offers a practical solution for maintaining flow integrity in outdoor watering setups.

Advantages

Constructed from steel for durability and resistance to mechanical wear, the clamp delivers a strong holding force and consistent tightening. The worm gear screw mechanism allows precise adjustment to match hose thickness and achieve a secure seal. The compact profile and straightforward design make installation and removal quick, reducing maintenance time on irrigation lines and garden hoses.

Suitable for

• Securing garden hoses to connectors and nozzles
• Clamping flexible pipes in watering systems
• Temporary or semi-permanent repairs to leaking hose connections
• Use in greenhouse irrigation and outdoor watering setups

Key specifications

• Material: Steel construction for strength and wear resistance
• Type: Screw (worm gear) clamp with adjustable band
• Nominal clamp diameter: approximately 5 cm (adjustable within a small range)
• Application: Designed for hoses and flexible pipes used in garden watering

How to use

Slide the clamp over the hose end, position the hose on the connector or pipe, then move the clamp into place over the joint. Turn the screw of the worm gear mechanism clockwise with an appropriate screwdriver to tighten the band until the hose is held firmly and no gaps remain between the hose and the fitting. To remove or loosen the clamp, turn the screw counterclockwise. Ensure the clamp is tightened evenly around the hose and avoid overtightening, which can damage softer hose materials.

Recommendations

For reliable performance, inspect the clamp and hose connection periodically for signs of corrosion or wear. Use the clamp within the compatible hose diameter range and avoid applying excessive torque when tightening. For long-term outdoor installations, consider occasional replacement if signs of rust or deformation appear to maintain leak-free operation.
