The Bestway Hose Adapters are a simple and effective way to give smaller Bestway pools larger pumping power by enabling more powerful filter pumps to connect to smaller pools, improving the flow of clean water. Two hose adapters are included to fit onto an inlet and outlet hose. These durable, corrosion-proof adapters connect hoses (Diameter 38 mm) to pool valves (Diameter 32 mm). The adapters are easy to install and come with an installation manual.
