## Summary description

Norma hose clamp with worm gear, model 73579, size range 140–160 mm. Steel construction with adjustable worm-drive mechanism provides secure clamping for hoses, ducts and pipe connections. Designed for automotive, industrial and plumbing applications where reliable, adjustable sealing is required. Easy to install with a screwdriver or socket, suitable for medium-diameter flexible hoses.

## Long description

Norma hose clamp with worm gear, size range 140–160 mm, is a steel adjustable clamp designed to provide secure fastening for medium-diameter flexible hoses, ducts and pipe connections. The worm-drive mechanism enables gradual tightening and reproducible clamping force, making it suitable for applications that require an adjustable seal. The clamp is compatible with screwdrivers or sockets for installation and is intended for automotive, industrial and plumbing environments where a robust metal clamp is needed.
Advantages
The steel construction ensures corrosion resistance and mechanical strength for repeated use. The worm gear allows precise adjustment across the 140–160 mm range, enabling a tight seal without damaging the hose. Installation is straightforward using common hand tools, and the uniform band profile distributes pressure evenly to reduce local hose deformation. The design provides reliable retention under vibration and temperature variation typical of engine bays and industrial systems.
Suitable for
Securing medium-diameter flexible hoses in cooling, intake or ventilation systems
Clamping ducting and pipe joints in plumbing and HVAC installations
Automotive hose connections subject to vibration and thermal cycles
Industrial machinery and equipment where adjustable metal clamps are required
Key specifications
Material: steel band and housing
Clamping range: 140–160 mm
Adjustment mechanism: worm gear (screw-driven)
Drive type: compatible with flat-head screwdriver or socket
Band width: suitable for medium-diameter hoses (standard narrow-to-medium band profile)
How to use
Place the clamp over the hose end and position the hose on the mating connection or pipe. Slide the clamp into the desired location so the band sits evenly around the hose, then engage the worm gear with a screwdriver or socket and turn clockwise to tighten. Apply gradual torque until the hose is compressed evenly and a leak-free fit is achieved; avoid over-tightening which can pinch or cut the hose. To remove, turn the drive counterclockwise until the band loosens and can be slid off the fitting.
Usage recommendations
Inspect the clamped connection after installation and after initial operation to confirm sealing; re-tighten if necessary within the specified clamping range. In corrosive or high-moisture environments, consider periodic inspection and use of corrosion-resistant variants if long-term exposure is expected. Use the clamp only on hoses and fittings compatible with a steel band to prevent damage.
