Clamp design

The Oetiker worm drive clamp is a technically sophisticated multi-range hose clamp with a very large Tension range. Hoses of various diameters can be securely connected with just one size.

The cold-formed bands of this clamp have a slightly convex shape. The height of the threads decreases on both sides - the full thread cross-section is in the centre.

The worm drive clamps of material quality W2 are equipped with a hexagon head screw (SW 7) with cross recess (Phillips). Clamps of material grades W3 and W4 have a hexagon head screw with slotted drive.

Installation recommendations

For professional installation, we recommend using a flexible screwdriver. This ensures secure installation even in places that are difficult to access. Electronically monitored torque screwdrivers should be used for series assembly where high process reliability is required.
