Fascetta a farfalla DeLOCK 400 SS 32 - 50 mm 5 pz. giallo

This DeLOCK 400 SS butterfly hose clamp is made of stainless steel and plastic and secures hoses with diameters from 32 to 50 mm without requiring tools. The set contains five 9 mm wide clamps in bright yellow, offering visibility and a firm hold under pressure for home, garden and light technical applications.

Advantages

The stainless steel construction ensures corrosion resistance while the plastic butterfly lever enables tool-free tightening and loosening. The 9 mm band width distributes clamping force evenly to reduce hose damage, and the bright yellow finish improves visibility during installation and maintenance.

Suitable for

• Automotive hose connections (low-pressure)
• Plumbing and garden hoses

Check that the clamp is seated correctly and retighten if necessary after initial pressure testing.

Recommendations

Do not use these clamps on high-pressure hydraulic systems. Inspect clamps periodically for wear or corrosion and replace if deformation or loss of clamping force is observed. For best performance, select the correct diameter range and avoid overtightening to prevent hose damage.
