Screw (Worm Gear) clamp Gardena 7193-20
The Screw (Worm Gear) clamp Gardena 7193-20 is a steel hose clamp with a nominal diameter of 4 cm designed for secure, adjustable hose connections in garden and repair applications. Manufactured by GARDENA, the clamp offers corrosion-resistant metal construction and a slotted band with a worm-drive screw for precise tightening. It is intended to create leak-free seals on flexible hoses, pipes and fittings where an adjustable, reusable fastening is required.
The steel construction provides mechanical strength and long service life in outdoor conditions. The worm gear screw enables gradual, controlled tightening for an exact fit while remaining user-serviceable and reusable. The compact dimensions and smooth band edge reduce the risk of hose damage during installation. The product's simple design makes it compatible with a wide range of flexible hoses and standard fittings used in garden watering systems.
Position the clamp around the hose end and the fitting so the band sits evenly over the hose reinforcement area. Turn the worm gear screw clockwise with a screwdriver to tighten the band until the hose is held securely against the fitting, avoiding overtightening that could cut or deform the hose. To loosen or remove, turn the screw counterclockwise. Check the connection after initial pressurization and retighten if necessary to ensure a leak-free seal.
For best results, select a clamp size that leaves some band overlap when fitted around the hose and fitting. Inspect clamps periodically in outdoor installations and replace if significant corrosion or band deformation is observed. Avoid extreme overtightening; the clamp should compress the hose sufficiently to prevent leaks without damaging the hose material.
