Hose Clamp Norma 20–32 mm, stainless steel, pack of 25

Norma hose clamp sized 20–32 mm, supplied as a pack of 25. This stainless-steel worm-gear clamp is designed to secure hoses and pipes with outer diameters from 20 to 32 mm. The adjustable band and screw drive allow incremental tightening to create a reliable seal between flexible hoses and fittings. The clamp is suitable for applications in automotive repair, plumbing and general workshop use where corrosion-resistant, reusable fastening is needed.

Advantages

The clamp's stainless-steel construction provides corrosion resistance and durability for repeated use. The worm-gear screw drive permits precise adjustment across the 20–32 mm range, enabling a secure fit on varying hose thicknesses. Supplied in a pack of 25, the set offers consistent quality and quantity for multiple repairs or installations without the need to purchase individual clamps.

Suitable for

• Securing coolant, fuel or vacuum hoses in automotive and small-engine maintenance
• Fastening flexible plumbing connections and water lines
• Workshop and industrial light-duty hose assemblies
• Temporary or permanent clamping where adjustable stainless-steel bands are required

Key specifications

• Diameter range: 20–32 mm (adjustable)
• Material: stainless steel band and housing
• Drive type: worm-gear screw drive
• Pack quantity: 25 pieces
• Finish: corrosion-resistant metal surface

How to use

Position the clamp around the hose so the band seats evenly against the hose surface and the screw housing sits clear of any obstructions. Thread the screw head clockwise to tighten until the required compression and sealing is achieved; avoid over-tightening that could damage the hose. To remove or reposition, turn the screw counterclockwise until the band loosens enough to slide off. Use a suitable screwdriver or nut driver compatible with the screw head for installation and removal.

Usage recommendations

For consistent sealing, select a clamp that allows comfortable tightening within the specified 20–32 mm range without forcing the band. Inspect clamps periodically for wear or corrosion in high-temperature or chemically aggressive environments, and replace if deformation or loss of clamping force is observed.
