Cabtyre cable outer diameters

How to check suitability of connector and cable size for CAPCON

For detail dimensions, see "Max. connector size" and "Applicable cable diameter" in the Specifications table above.


  1. Process the mounting surface for making a hole or cut threads.
  2. Attach the cable gland CAPCON to it.


3. Remove the Dome nut, W-seal and Rubber bushing.


4. Run a connector cable through in order of the Dome nut, W-seal and Nipple.


5. Open the slit of Rubber bushing to let the cable in and then fit the W-seal.


6. Tighten the Dome nut to fasten cable securely

  • Use only one cable for one hole.
  • Tightening torque and tensile strength differ depending on the material of cable coating and its hardness.
  • Tensile strength and waterproof performance drops when outer cable diameter changes due to aging.
  • Product performance are not guaranteed for cables other than the applicable size or round cables.
  • For proper torque management of the locknut and the dome nut , fix the nipple with a wrench and tighten the Dome nut.
