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.
Compression fittings use a soft metal or thermoplastic ring (the compression ring or ferrule) which is squeezed onto the pipe and into the fitting by a compression nut. The soft metal conforms to the surface of the tubing and the fitting, and creates a seal.
