Tips

Use a proper crimping tool sized for 4 mm² terminals to ensure a gas-tight connection. Slide heat-shrink tubing over the barrel before crimping if insulation is required. For high-vibration environments, consider applying a second crimp or soldering after crimping for added mechanical strength.
