Hayward 2 Port, 4 Gear Module with O'Ring

The Hayward 2‑Port, 4‑Gear Module with O‑ring is a replacement internal cartridge designed for use in Hayward in‑floor cleaning water valves, restoring proper sequencing and flow distribution to two‑zone systems. Its four‑gear drive assembly uses water pressure to rotate smoothly and consistently, ensuring each zone receives balanced flow for effective cleaning performance. The included O‑ring provides a reliable seal when the module is installed in the valve housing, helping maintain pressure and prevent leaks. Built from durable, chemical‑resistant materials, it’s engineered for long service life and straightforward maintenance. Based on similar Hayward gear modules, the estimated weight typically falls in the 0.5–1.0 lb range.
