A pneumatic compression pump is a basic component of intermittent pneumatic compression (IPC), a widely used technique that involves attaching an electrical air compression pump to an inflatable plastic garment that is placed over the affected limb.
Slide the compression nut to the end of the pipe and screw it onto the compression fitting. Tightening the nut squeezes the compression ring/ferrule into the seat and against the copper pipe, making a watertight seal. Hand tightening may be enough, but if you get some drips you can tighten the joint using a wrench.
