Hayward NUT AND WASHER UV/HYDRA

The Hayward Nut and Washer for UV/Hydra systems is a small hardware set designed to secure key components within Hayward’s ultraviolet and Hydra‑series sanitization assemblies, ensuring stable alignment and a reliable seal where fittings or housings join. These pieces are typically made from corrosion‑resistant materials capable of withstanding moisture, heat, and treated‑water environments, helping maintain long‑term structural integrity around sensitive UV or flow‑control components. Their precise sizing supports proper tension and prevents loosening from vibration or thermal expansion during operation. Because the set consists of only a nut and washer, both compact metal or polymer parts, the estimated combined weight generally falls in the range of 0.02 to 0.08 pounds.
