Double wires hose clamps are made of double strand steel wire with high resistance; they are coated with a preservative zinc plating, which ensures a practically unlimited durability.
In comparison with other clips and clamps, they have the following advantages:
•The stress on the plastic or rubber hose caused by the double strand clamps is obviously lower - through the clamping action is the same - than the one caused by the single wire clamps; in fact the radial load is distributed over a wider surface of the hose (see pictures A and B).
•Furthermore, the roundness of wire of which the wire clamps are made allows the cutting action, when compared with the one produced by the regular boot clamps (see pictures A and C), to be much lower, it ensures a longer durability of the flexible hoses and a higher resistance of blow-off.
4)screw length:from 30mm to 80mm
5) wire material: 65Mn spring steel
6) screw material: zinc coated steel or stainless steel
7)usage:on car/air/plumbing/irrigation pipes or hoses
W1=the wire is 65Mn spring steel only,others are galvanized steel
W4=the wire is 65Mn spring steel only,others are 304 stainless steel
Remark:You could choose 11-14mm size of this wire clamps if the outer diameter of the pipe you used is about 12mm.
