perfect compatibility: the ball bearing of the pipe can be rotated and replaced Quality Enhancement: The pool cleaner hose is made of high quality materials and has been rigorously tested by the manufacturer to prevent leaks. To connect 2 supply pipes together, 2 pipe nuts and 1 swivel joint of hose are required. Solve problems: 1) Rotating wear. 2) Part of the gasket is leaking. 3) The pipe becomes stiff and cannot rotate freely. Installation tips: The arrow always points in the direction of the water flow. Water flows from the wall fittings through the hoses to the Polaris pool cleaner. The pipe end can be softened by immersing the pipe end in a container (pot or large insulated coffee cup) containing real hot water, which allows it to be easily slid into the device. Easy to install: The pool cleaner hose is easy to install, quick to connect, saving time and money.
