- Secure performance: The advanced locking ring design actively prevents air leaks, crucial for maintaining hydraulic pressure in hot weather months. Replaces warped or poorly sealed lids to reduce pump load and extend equipment life. Ensures uninterrupted filtration for clear water. - Long-term reliability: Made from high-quality composite material, this lid replacement prevents leaks and air bubbles in the filter system and supports smooth operation. Anti-rust properties improve durability, while frost-crack tolerance supports year-round use. - Easy installation: A straightforward replacement process. Shut down the system, remove the existing locking ring, and secure the new component. No special tools or technical expertise required. Proper protection of the pump housing when installed correctly. - Flexible application: Smooth outer surface minimizes damage during installation, while symmetric eyelets provide stability and user-friendly handling. Designed for a secure fit and durable protection of your pump system. - Use scenarios: Replace the lid at the start of the pool season to restore filtration efficiency. Use during hot months to maintain hydraulic pressure and water clarity. Ideal for year-round use in climates with freezing temperatures due to frost-crack tolerance.
