Test torques at 20°C
(1)
The tests of clamping ranges and torque values were performed with metal mandrel. The clamping range can vary by using cables with different manufacturing tolerances
and material properties. Please use the combination of sealing 1 + 2 + 3 for the intermediate region.
(2)
When selecting the seal rubber, ensure that the cap nut can be tightened when carrying out any future maintenance work on the cable entry.
