Embossed worm gear hose clamps are popular, economy and precision-engineered to use in many general applications, available in 9mm and 12mm band width. Also called worm drive hose clamps, DIN3017 non-perforated worm gear hose clamps(germany type), or German type hose clamps. They has excellent performance while being at the same time very compact. The smooth non-perforated band and flared edge prevent soft silicone hoses from shearing or extruding during installation.
EMBOSSED WORM GEAR HOSE CLAMPS complies fully with the DIN 3017 norm and also with the RoHs &Reach.Material and clamping range and your logo can be stamped on the band.
