Material thickness
Oetiker StepLess® Screw Clamps and Self-Tensioning StepLess®
Screw Clamps are made from strip material 9 mm wide and
0.6 mm thick. The dimensions of the strip ensure optimum sealing
with EPDM rubber and silicone hoses, while taking into account
the necessary radial force, the compressibility of the hose, the
sealing/retaining properties and the environmental conditions.
Interlock
The closure is a mechanical interlock whose function is to provide
secure retention of the round clamp geometry. The interlock
can be opened to permit radial assembly of the clamp, and at
the same time provides a simple way of relocating the interlock
features to obtain alternative diameters prior to tightening.
