[Improved Water Circulation] Replace your old plunger valves with these two connectors, or upgrade your existing plunger valve system to improve water circulation. Changing hoses and pump becomes easier, and your pool maintenance is optimized. [Wide Compatibility] This pool hose connector is compatible with pools from brands such as Intex, Hayward, and Coleman.
