Capillary tubing or capillary tubes are very thin tubes made of a rigid material, such as copper, plastic or glass in which a liquid flows up into the tubes against gravity in a process called capillary action (capillarity). Capillarity is the movement of a liquid in a small cross sectional capillary passage tube such as the openings in porous materials.
