## Long description

Norma worm-drive hose clamp model 73580 is a metal fastening clamp designed for secure attachment of flexible hoses and ducting with an adjustable diameter range of 160–180 mm. Constructed from corrosion-resistant metal, the clamp uses a threaded worm gear mechanism for controlled tightening and reliable grip. It is suitable for HVAC, plumbing and industrial duct connections where a wide adjustment range and robust fastening are required.
Advantages
The worm-drive mechanism provides uniform compression around the hose, allowing incremental tightening and dependable sealing. Corrosion-resistant metal construction ensures durability in indoor and sheltered outdoor environments. Its broad 160–180 mm diameter range covers a variety of hose and pipe outer diameters, reducing the need for multiple clamp sizes. The simple screw adjustment enables quick installation and maintenance using common tools.
Suitable for
 HVAC duct and ventilation hose connections
 Plumbing flexible hose fastening
 Industrial ductwork and exhaust systems
 General-purpose hose and tubing attachment where wide diameter adjustment is needed
Key specifications
 Clamp type: Worm-drive hose clamp
 Material: Corrosion-resistant metal
 Adjustable diameter range: 160–180 mm
 Tightening mechanism: Threaded worm gear with screw drive
 Typical applications: Hoses, ducting, ventilation and exhaust connections
How to use
Position the clamp over the hose or duct so that the band fully encircles the fitting and the worm housing is accessible. Rotate the screw mechanism clockwise with a screwdriver or compatible tool to tighten until the clamp exerts even pressure and the hose is secured against the fitting. Avoid overtightening to prevent damage to flexible hoses; ensure a firm, leak-free connection. To remove or readjust, turn the screw counterclockwise until the band loosens and can be slid off.
Usage recommendations
For long-term installations, verify material compatibility between the clamp and the hose or pipe, and check the clamp periodically for corrosion or loosening. Use appropriate torque and avoid sharp edges under the band; if the hose material is soft, consider using a protective sleeve under the clamp to prevent deformation.
