Recommended Filtration100 micron



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.  

Gems also offers the FS-380B Compact Flow Switch, which features a unique dual connection port that provides 1/2˝ NPT and 1/4˝ push-to-connect fittings.
