When to Replace Your O-Ring

O-rings in pool heating systems are continuously exposed to heat, pressure fluctuations, and pool chemicals. Over time, they become brittle, compressed, or cracked, causing leaks around connections and joints. Fitting a genuine Zodiac replacement O-ring restores the original seal quality and is essential for safe, efficient operation of your heating equipment.

Installation Advice

Before fitting, ensure the seating surface is clean and free of debris. Lightly lubricate the O-ring with a silicone-based grease to ease installation and improve the initial seal. Always depressurise and drain the heating circuit fully before beginning any work. Verify the part number against your equipment’s exploded view diagram before ordering.
