PISTON TYPE FS-380P Series - Industrial Strength Inline Plastic Flow Switch Flow Rate Settings: 0.25 GPM to 2.00 GPM Port Size: 3/8 NPT Male and 1/4 Quick Disconnect (QDC) Male Primary Construction Material: Polypropylene Setting Type: Fixed This rugged inline flow switch offers the same superior performance to non-clogging as its metal cousin (FS-380). The fixed set point and simple design make it a dependable switch. The FS-380P is an ideal choice for coolant applications requiring reliable flow detection in HVAC, semiconductor, welding, medical and other industries. 1/4 quick disconnect units have a host of snap-on mating adapters to fit most piping requirements.
