Hose Clamp Norma 25–40 mm, stainless steel, pack of 25

Norma hose clamp with an adjustable diameter of 25–40 mm supplied as a pack of 25 pieces. The clamp features a machined worm-drive band and a stainless steel construction that resists corrosion and provides reliable clamping force for flexible hoses, pipes and ducts. Designed for plumbing, automotive and general repair tasks where a corrosion‑resistant adjustable clamp is required to seal and hold flexible tubing.

Advantages

The machined worm-drive offers even engagement across the band for consistent sealing and reduced risk of slippage. Stainless steel construction ensures durability and resistance to rust in wet or corrosive environments. The 25–40 mm adjustable range covers common hose sizes used in domestic plumbing and many automotive and equipment applications. Supplied in a pack of 25, the clamps provide value for projects and maintenance jobs that require multiple fasteners.

Suitable for

• Securing flexible hoses in plumbing installations (sinks, drains, appliance connections)
• Automotive hose connections such as coolant, fuel return and vacuum lines where diameter fits
• HVAC ducts and ventilation where a compact adjustable clamp is needed
• General repair and maintenance tasks requiring corrosion‑resistant hose clamps

Key specifications

• Adjustable diameter: 25–40 mm
• Material: stainless steel (band and housing)
• Drive type: machined worm-drive
• Pack contents: 25 identical clamps
• Typical applications: plumbing, automotive, HVAC, general repairs

How to use

Position the clamp around the hose and mating fitting so the band sits evenly on the hose surface. Engage a suitable screwdriver or nut driver with the screw head and turn clockwise to tighten until the hose is secure and a leak‑tight seal is achieved; avoid over‑tightening which can damage flexible tubing. To remove, turn the screw counterclockwise until the clamp can be slid off. Inspect clamps regularly in applications exposed to vibration or temperature cycling and retighten if necessary.

Usage recommendations

Choose the clamp diameter so the hose sits within the 25–40 mm range when installed. For critical fluid systems, verify compatibility of stainless steel with the media being conveyed and consider periodic inspection for wear or deformation. Use a properly sized driver to prevent stripping the screw head.
