Single Line Y-Tube System Considerations

Single line Y piping systems use a common material line for all vacuum receivers connected to a pump and are typically used to convey material from a central supply to several stations.

If you are installing a single line Y system, use Y tubes on the material lines. A Y tube is installed with the branch arm leading to the next station on top and the straight portion that supplies material to the station underneath.

Connect a short-radius bend to the straight portion as close to the Y as possible.

You must connect a minimum 2-foot (61 cm) straight length of tube to this short radius bend on the horizontal before the material tubing drops to the receiving point. If possible, incline this tube approximately 1/8” per foot (1 cm per meter).

On single line Y systems, you must install check valves on material inlet tubes inside vacuum receivers.

Note: Do not use SSR03 or SSR06 vacuum receivers on single line Y systems.

You can install a long- or short-radius bend on the last station, where a Y-tube is not needed.
