Screw (Worm Gear) clamp Gardena 7197-20

The Gardena 7197-20 screw (worm gear) clamp is a steel fastening solution designed for hoses with a diameter of 1.1 cm. Its simple construction provides consistent clamping force around flexible tubing, creating a tight connection between hose and fitting to reduce leaks and slippage in garden and irrigation systems. The clamp's materials and design focus on everyday reliability and corrosion resistance appropriate for outdoor use.

Advantages

The steel screw and band deliver secure, adjustable pressure that can be finely set for a precise fit on small-diameter hoses. The worm gear mechanism allows controlled tightening and re-tightening without damaging the hose when used correctly. The compact profile and robust build help maintain a long service life under normal garden and household conditions.

Подходит для

• Соединение гибких садовых шлангов диаметром около 1.1 см с фитингами
• Фиксация трубок в системах полива и орошения
• Ремонт и замена креплений в бытовых и садовых проектах

Key specifications

• Material: steel band with screw mechanism
• Designed hose diameter: 1.1 cm
• Closure type: worm gear (screw) clamp
• Adjustable clamping range suitable for small-diameter flexible hoses
• Surface finish: corrosion-resistant treatment for outdoor use

How to use

Slide the clamp over the hose end, seat the hose onto the fitting, position the band so it sits directly over the fitting barb, and tighten the screw using an appropriate screwdriver until the hose is firmly engaged on the fitting. Avoid over-tightening to prevent cutting or deforming the hose. For a secure connection, check the joint under pressure and, if necessary, slightly adjust the clamp tension.

Usage recommendations

Inspect the clamp and hose periodically for corrosion or wear, especially in outdoor installations; replace the clamp if the band or screw shows significant damage. Use the clamp only on hoses near the specified diameter and choose a slightly larger or different clamp style for thicker or rigid tubing.
