Item Description ▼
The NORMACLAMP® S Sz W1 hose clamp according to DIN 3017 is the reliable solution for fastening rubber and plastic hoses as well as rubber sleeves to pipe ends or hose connectors. Thanks to its robust jaw construction with hex head screws (Sz), it achieves a high degree of compression and ensures uniform contact pressure even with medium and larger diameters.
The NORMACLAMP® S Sz W1 is available in bandwidths of 9 mm, 12 mm, 15 mm and 20 mm and covers a wide diameter range. The W1 material (galvanized steel) offers solid corrosion resistance of at least 72 hours in the salt spray test. The step size is 1 mm, which allows for precise adaptation to the respective hose. Multi-part versions are available for clamping large diameters.
- High compression degree – due to robust jaw construction with hex head screws (Sz)
- Uniform contact pressure – for reliable tightness
- Optimal hose protection – through integrated bridge
- Rounded band edges (from 20 mm bandwidth) – prevents injuries and hose damage
- Multi-part design available – for clamping large diameters
- Angles, brackets or tabs can be attached
- Can be equipped with rubber profile – for vibration damping and protection against creeping water
- Standard-compliant – according to DIN 3017
- Fastening of rubber and plastic hoses
- Fastening of rubber sleeves to pipe ends or hose connectors
- Fastening of airbags in the automotive industry (100% tested safety parts)
- Wherever a high degree of compression and reliable tightness are required
- NORMACLAMP® S Sz W1 hose clamp in the selected variant (diameter & bandwidth)
