This German-style Butterfly Handle Hose Clamp combines the reliable sealing performance of a worm-drive clamp with the convenience of a thumb-operated handle. It is engineered for applications where quick adjustments and secure fastening are essential, eliminating the need for separate tools during installation or maintenance.
The design features a non-perforated band that provides 360-degree sealing pressure. This protects soft silicone or rubber hoses from being crushed or cut, ensuring the integrity of your connection and preventing leaks under fluctuating pressure.
The integrated butterfly handle allows for rapid tightening and loosening by hand, significantly reducing assembly time in the field or on the production line.
The smooth, non-perforated inner surface of the band ensures uniform clamping force, protecting hoses from damage and maintaining a stable, leak-proof seal.
Crafted from high-quality Stainless Steel 201 or 304 with a polished finish. This offers excellent resistance to rust and corrosion, ensuring a long service life even in demanding environments like marine or agricultural settings.
The precision-engineered worm drive mechanism ensures a tight, secure grip that remains locked in place, resisting loosening caused by vibration.
Our clamps are available in two distinct bandwidths to suit different hose types and pressure requirements. Below are the standard size ranges. Please refer to the detailed specification table for the full list.
