Application These well point drive caps and couplings are used with well points to create a shallow well without digging. Function The well point drive caps are screwed onto the threaded end of the well point to protect the threads from damage when the well point is driven into the ground. Threaded well point couplings allow sections of threaded pipe to be connected to the well point. When the well point is driven into the ground additional sections of pipe are connected to the well point and driven into the ground to increase the depth of the well. Material .
