A foreline is a vacuum line between the pumps of a multistage vacuum system. No longer exclusively used by scientists in research, vacuum systems are used in numerous industries that include food production and the manufacturing of electronic components. A classic foreline is a hose or tube that connects a rotary vane pump to the outlet of an oil diffusion pump, although vacuum technology now uses a vast array of roughing pumps and high vacuum pumps.
