Perfect Compatibility: The hose's ball bearing can be rotated and replaced, making it perfect for Polaris 180, 280, 380, 480, and 3900 pool cleaners. Part Number: D20, D-20 (Note: Not suitable for Polaris 360 POOL CLEANER). Improved Quality: The pool cleaner hose is made of high-quality materials and has undergone rigorous testing by the manufacturer to prevent leaks. Two pipe nuts and one swivel joint are required to connect two supply pipes. Troubleshooting: 1) Rotating wear. 2) Part of the connection is leaking. 3) The pipe becomes rigid and cannot rotate freely. Installation Note: The arrow always points in the direction of water flow. Water flows from the wall fixtures through the pipes to the Polaris pool cleaner. The hose end can be softened by immersing it in a container (a pot or large insulated coffee mug) filled with hot water, allowing it to slide easily into the unit. Easy to install: The pool cleaner hose is easy to install and connect quickly, saving time and money.
