china German Hose Clamps manufacturer
Compliant with DIN 3017 and QC/T620 standards
HWKG German style worm drive hose clamps are heavy-duty pipe fasteners for bulk OEM procurement, extensively applied in construction, mechanical engineering and household equipment assembly. Featuring outstanding anti-corrosion, heat-resistant and high-tensile performance, these industrial clamps adopt unique non-through-hole tooth profiles.
The worm gear transmission structure delivers uniform clamping force; the non-perforated tooth design efficiently transfers fastening torque while avoiding hose abrasion during installation. Two mainstream structures, welded integrated and split assembly types, are available to satisfy diverse project specification demands. Rolled smooth band edges further eliminate scratch risks caused by long-term hose contact for long-term stable pipeline operation.
