## Long description

Norma hose clamp model 73578 is an adjustable stainless-steel clamp with a worm gear designed to secure hoses and tubes with diameters from 120 to 140 mm. The screw-driven band provides mechanical tightening that ensures a consistent compression force around the hose, creating a reliable seal in plumbing, HVAC, automotive and light industrial assemblies. The clamp is intended for use where a robust, re-adjustable connection is required and can be installed or removed using a screwdriver or nut driver.
Advantages
The worm gear mechanism offers precise and gradual tightening, allowing accurate adjustment to the required tension. Constructed from corrosion-resistant metal, the clamp maintains clamping force over repeated service cycles and resists environmental exposure typical for plumbing and vehicle engine compartments. Its wide diameter range covers several hose sizes, reducing the need for multiple clamp types and simplifying inventory. The band design distributes pressure evenly to reduce hose damage while maintaining an effective seal.
Suitable for
Sealing flexible hoses in plumbing and drainage systems
Securing air and coolant hoses in automotive repair and maintenance
Fastening ducting and tubing in HVAC installations
Temporary or permanent hose connections in light industrial equipment
Key specifications
Clamping range: 120–140 mm (adjustable)
Type: Worm gear hose clamp (screw-driven band)
Material: corrosion-resistant metal
Installation: screwdriver or nut driver compatible
Design: continuous band for even pressure distribution
How to use
Position the clamp over the hose end and slide the hose onto the fitting or barb to the desired depth. Place the clamp so the band sits evenly over the hose and the worm gear housing aligns with accessible clearance for the tool. Tighten the screw using a cross-head screwdriver or appropriate nut driver until the hose is firmly seated and the seal is leak-free; avoid over-torquing to prevent hose deformation. To remove or reposition the clamp, loosen the screw until the band relaxes and then slide the clamp away from the connection.
Usage recommendations
Check compatibility of hose material and diameter before installation. For applications involving fuel, high pressures or aggressive chemicals, verify material suitability and consider clamps or fittings rated for those conditions. Periodically inspect clamped joints for corrosion, loosening or hose wear and re-tighten or replace the clamp as required to maintain a reliable seal.
