Polaris 6-505-00 Quick Disconnect O-Ring – For Polaris Universal Wall Fitting (UWF) Connections

The Polaris 6-505-00 is a replacement O-ring seal used on the Polaris quick disconnect connection at the Universal Wall Fitting (UWF). This O-ring helps create a tight seal between the wall fitting/quick disconnect and the cleaner hose connection to prevent leaks, reduce spraying, and maintain strong water flow for proper cleaner performance.

Key Features

  • Part Number: 6-505-00
  • Part Type: Quick disconnect O-ring / seal
  • Application: Polaris UWF wall fitting quick disconnect connection
  • Function: Helps prevent leaks and pressure loss at the wall connection
  • Sold As: 1 O-ring

Common Signs It’s Time to Replace

  • Water spraying or leaking at the wall quick disconnect
  • Cleaner feels weaker than normal due to pressure loss at the wall connection
  • O-ring looks flattened, cracked, swollen, or brittle
  • Quick disconnect feels loose even when fully seated

Installation Notes

  • Turn off the pump before disconnecting the cleaner hose.
  • Remove the old O-ring and clean the sealing groove/surfaces to remove grit and scale.
  • Lightly lubricate the new O-ring with silicone pool lube (do not use petroleum-based grease).
  • Reinstall and confirm the connection seats fully and does not leak when running.

Installation & Maintenance Tips

  • Keep the wall fitting screen/filter clean—restricted flow can increase turbulence and make leaks more noticeable at the connection.
  • Use only a light film of silicone lube on the O-ring; excess lubricant can attract dirt and shorten seal life.
  • If you still see spraying with a new O-ring, inspect the quick disconnect body for cracks, warping, or worn sealing surfaces.
  • Store the cleaner and hose out of direct sun when possible to reduce UV damage to plastics and seals.
