D High Torque Worm Drive Clamp 

The NORMACLAMP® HD is a high strength worm drive hose clamp completely made of stainless steel. It is the most powerful hose clamp within the NORMA® product range and is therefore ideally suited for heavy duty and high pressure applications where high tightening forces and high contact pressures are essential.

The extended band prevents the hose from protruding and being damaged. The design has a recommended tightening torque of 17.00 Nm, which is about twice of the tightening torque of a conventional worm drive hose clamp.

A major feature is the one piece extended band liner to protect the hose from damage caused by extrusion and shearing of the hose through the worm drive slots. An advantage over other heavy duty bolt clamps is the wide clamping range (approx. 20mm for each clamp).
