General Specifications

The 5-21-PP Straight Body Flow Switch offers unmatched affordability and reliability for OEM low-flow sensor applications. This no-nonsense flow switch is available with five factory-set flow rates:

  • 0.1 GPM,
  • 0.25 GPM,
  • 0.5 GPM,
  • 0.75 GPM, and
  • 1 GPM.

For ultra-low flow sensing, the switch can be mounted vertically without the titanium spring. Its design includes built-in 9/16 UNF female bosses that can be paired with four accessory fittings, which serve as a stop for the flow switch poppet and spring in the outflow port.
