## Summary description

Worm-drive hose clamp Norma model 73584 with adjustable diameter range 220–240 mm. Metal band clamp designed to secure hoses, pipes or ducts by tightening a worm gear screw; suitable for industrial, automotive and HVAC applications where a robust, adjustable fastening is required. Provides uniform clamping pressure and simple screw adjustment for installation and maintenance.

## Long description

Norma worm-drive hose clamp model 73584 is a metal band clamp with an adjustable diameter range of 220–240 mm designed to secure hoses, pipes and ducts where a reliable mechanical fastening is required. The clamp uses a worm gear screw to convert rotational motion into linear movement across the band, producing uniform clamping pressure and allowing easy manual adjustment during installation and maintenance.
Advantages
The hose clamp provides consistent, even pressure around the hose circumference to reduce the risk of leakage and slippage. Constructed from corrosion-resistant metal components, it is suitable for repeated tightening and loosening without loss of grip. The worm-drive mechanism enables precise tension control through a standard screwdriver or nut driver, and the wide diameter range covers a variety of hose and pipe outer diameters within the 220–240 mm span.
Suitable for
Securing large-diameter rubber or silicone hoses in automotive and heavy equipment systems
Clamping ventilation ducts and flexible air hoses in HVAC installations
Fastening hoses and pipes in industrial process lines and machinery
Temporary or permanent connections where adjustable metal band clamps are required
Key specifications
Clamping diameter range: 220–240 mm
Type: Worm-drive (screw) hose clamp
Material: Metal band with screw-driven housing (corrosion-resistant finish)
Adjustment method: Screw/worm gear operated with standard screwdriver or nut driver
Application environment: Suitable for automotive, HVAC and industrial use
How to use
Position the clamp around the hose or duct so the band seats evenly against the hose outer surface and the screw housing is accessible. Rotate the screw clockwise with a screwdriver or nut driver to reduce the clamp diameter until the hose is firmly secured against the fitting or pipe. Avoid over-tightening; tighten until a secure seal is achieved without deforming the hose material. To remove or readjust, turn the screw counterclockwise to increase the diameter and slide the clamp off or reposition as needed.
Usage recommendations
For reliable performance, select the clamp so the hose outer diameter sits well within the 220–240 mm range rather than at either extreme. Inspect the clamped joint after initial operation and periodically during service for signs of corrosion, loosening or hose damage. Use the correct tool size and apply moderate torque to prevent stripping the screw head or damaging the hose.
