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.

Acetal Adapters for 1/4˝ Quick Disconnect
Male Tube Fitting Units (180°F max.)

These adapters are available with or without an integral
shut-off valve. The shut-off valve will stop line flow
when the adapter is removed from the unit. Flow
resumes when connected.
