The Ruelco hydraulic 3-way tattletale is a compact device that provides indication when a hydraulic sensor or control component operates. The 3-way tattletale is designed to be installed in the return line near the exhaust port of a hydraulic sensor or control component. When the sensor or control device operates and vents or exhausts hydraulic fluid, the pressure in the return line will cause the cap of the 3-way tattletale to pop up. This exposes a red indicator band, giving visual indication that the sensor or control device has operated.
