Insert ferruled conductor into crimping station.

Squeeze handles until ratchet mechanism is released.

What is “gas-tight?” Elevated resistance is detrimental for signal transmission,
In a gas-tight connection, the conductor and the ferrule are as the signal flow is damped (weakened), and for power
