Abstract
A vacuum probe comprises a sharpened body that is displaceable downward and toward a vacuum bag during vacuum hose quick connection. The sharpened body and a valve element inside the vacuum probe move in tandem until the sharpened body projects outside the vacuum probe. A vacuum pressure applied via the vacuum hose pulls the vacuum bag upwards and towards the projecting sharpened body, which then punctures the vacuum bag, thereby enabling air under the vacuum bag to be evacuated via the vacuum probe as vacuum pressure continues to be applied.
