FS-380 Series - Compact Flow Switch for High Inline Pressures Flow Rate Settings: 0.15 GPM to 2.00 GPM Port Size: 3/8 NPT Male Primary Construction Material: Brass or Stainless Steel Setting Type: Fixed These rugged inline flow switches use 100 micron filtration and are less susceptible to clogging than other high-pressure inline flow switches. The one-piece magnetic PPS composite piston makes the FS-380 ideal for high-pressure applications such as industrial cleaning equipment. The FS-380 is also an excellent choice for semicon cooling applications where simple design and reliable operation are required. Specifications U.L.
