## Summary description

Norma worm-drive hose clamp for securing hoses and tubes with a clamping range of 16–27 mm. Made of stainless steel with an adjustable screw mechanism for reliable sealing and corrosion resistance. Supplied as a pack of 25, suitable for plumbing, automotive, HVAC and general workshop use where a durable adjustable hose clamp is required.

## Long description

Norma worm-drive hose clamp with an adjustable stainless steel band designed for clamping hoses and tubes with a diameter range of 16–27 mm. The clamp uses a worm-gear screw mechanism to provide uniform compression and a reliable seal. Supplied as a pack of 25, this item is intended for applications that require corrosion resistance, repeated adjustment and secure fastening of flexible connections in plumbing, automotive, HVAC and workshop environments.
Advantages
The stainless steel construction ensures resistance to rust and extends service life in damp or outdoor conditions. The worm-drive screw allows fine adjustment across the 16–27 mm range for consistent clamping pressure and tight seals. Supplied in a multi-pack, the clamps offer cost-effective replacement and the ability to fit multiple hoses at once. The simple design enables quick installation with common screwdrivers or nut drivers.
Suitable for
Securing coolant and fuel hoses in automotive maintenance
Fastening flexible hoses in plumbing and drainage systems
Connecting ducting and hoses in HVAC installations
General workshop and machinery hose retention
Key specifications
Clamping diameter range: 16–27 mm
Material: stainless steel band and housing
Adjustment type: worm-drive screw mechanism
Drive head: slotted/flat or compatible screw head for common screwdrivers
Quantity: pack of 25
How to use
Position the clamp over the hose end so the band sits evenly around the connection. Turn the worm-drive screw clockwise to tighten until the clamp provides a firm seal without crushing the hose. To loosen or remove, turn the screw counterclockwise. Use a properly sized screwdriver or nut driver and avoid over-tightening to prevent damage to the hose or clamp threads. Inspect the sealed joint after initial pressurization and re-torque if necessary.
Usage recommendations
For best performance, select a clamp where the nominal hose diameter falls well within the 16–27 mm range rather than at the extreme limits. For high-vibration or high-pressure applications, inspect clamps periodically and replace if signs of corrosion or thread wear appear.
