Hose Clamp Norma Opaska ślimakowa 25–40 mm

Norma Opaska ślimakowa 25–40 mm is a stainless steel hose clamp with a worm-drive mechanism designed to secure hoses with diameters from 25 to 40 mm. Made by Norma, this clamp is intended for reliable fastening of rubber and PVC hoses in automotive, plumbing and light industrial applications. Its adjustable band and screw-driven tightening allow for controlled compression for leak-resistant connections and improved resistance to vibration.

Advantages

The stainless steel construction provides corrosion resistance for use in wet and humid environments while maintaining mechanical strength. The worm-drive screw enables precise adjustment and consistent clamping force, suitable for varying hose thicknesses within the 25–40 mm range. The smooth band edge reduces the risk of hose damage during installation, and the compact design allows installation in confined spaces where reliable hose connections are required.

Suitable for

• Securing rubber coolant and heater hoses in automotive systems
• Fastening water and drainage hoses in plumbing repairs
• Attaching vacuum and air lines in light industrial equipment
• Temporary or permanent hose connections for irrigation and garden systems

Key specifications

• Material: stainless steel band and housing
• Adjustment range: 25–40 mm nominal hose diameter
• Drive type: worm-drive screw for tool-adjustable tightening
• Band width: suitable for standard hose profiles (compact design)
• Intended hose types: rubber and PVC hoses

How to use

Position the clamp around the hose over the fitting or barb, ensuring the band sits evenly and the hose is pushed fully onto the connector. Use a suitable screwdriver or socket to turn the worm-drive screw clockwise until the clamp applies uniform pressure against the hose without deforming it. Avoid over-tightening which can cut into the hose material; back off slightly if the hose shows visible compression. To remove, turn the screw counterclockwise until the band loosens and the clamp can be slid off.

Usage recommendations

Inspect the hose and connector before installation for damage or debris. For applications exposed to corrosive environments or constant vibration, periodically check clamp tightness and condition and replace clamps showing signs of corrosion or wear. Select the clamp if the hose diameter falls within the 25–40 mm range and the hose material is compatible with stainless steel contact.
