The D is a very strong worm gear clamp with a bandwidth of 9mm. This hose clamp complies with the European standard DIN 3017 and resists large torques. This standard guarantees that the hose joins the connecting pipe end in a perfect tight fit.
The band of this worm gear clamp is pressed, non-perforated, folded up at the edges and has smooth inner surface. This makes sure that the hose clamp does not damage the hose. This worm gear clamp resists large torsional forces well and is not deformed due to the radial and axial forces which act during fixing.
