Quick connect devices serve as inline connect/disconnect points and/or vacuum termination points. When disconnected the connections without valves allow vacuum pressure to equalize, which is ideal on the pump side, allowing it to relax when not in use. The connections with valves maintain vacuum pressure when released.
Simple connection: A hose from a chamber can be easily connected to a hose on the pump without having to pull the hose off a barb each time. It can save wear and tear on lids.
Backflow valve use: To use a chamber and maintain vacuum with an open port a short tube and valve will hold without connection. This is also very useful when hunting leaks and isolating a component.
