The screw-on end is engineered to bite directly into the inner metal or plastic spiral of common flexible ducts.
A firm twist ensures a tight engagement and prevents air leaks.

⚠️ Important: Flexible PVC ducts do not all use the same spiral direction.
Make sure to check the winding direction of your hose before selecting a model.
Choosing the correct CW/CCW version is essential to ensure the connector properly bites into the inner spiral and seals correctly.
