The Hayward GLX‑FLO‑25 .5 MPT Flow Switch with 25' Cable is a genuine OEM water flow sensor engineered to ensure safe and reliable operation of pool and spa equipment that depends on proper circulation. Installed in the return line with a .5" male pipe thread (MPT) connection, this flow switch detects adequate water movement and sends a signal to the control system allowing pumps, heaters, and chlorinators to run only when safe flow is present.

Featuring a 25‑foot direct‑connected cable, the GLX‑FLO‑25 offers installation flexibility and easy integration into equipment pads and control wiring. It’s built to withstand pool environments, delivering durable, accurate flow sensing to protect your system from low‑flow or dry‑run conditions that could damage internal components.
