Most airless spray equipment uses a high pressure paint hose between the airless pump and the airless spray gun, excluding handheld airless paint sprayers which naturally do not use high pressure airless paint hose.

The most common internal diameter airless paint spray hose is 1/4 inch or 6 mm ID.
