Bestway Hose Adapters are a simple and effective way to give smaller legendary pools more pumping volume by enabling more powerful filter pumps to connect to smaller pools, improving clean water flow. Two hose adapters are included to fit the inlet and outlet hose. These durable, corrosion-resistant adapters connect hoses (38mm diameter) to assembly valves (32mm diameter). The adapters are easy to install and come with an installation guide.
