The Pentair Pool Cleaner Reducer Cone GW9015 creates a tight, reliable seal between cleaner hoses and compatible suction-side pool cleaners, preventing air leaks that reduce cleaning power. This critical component ensures consistent performance and keeps your cleaner moving efficiently across the pool floor. Built as a genuine OEM replacement, it restores proper hose fitment without guesswork or makeshift adapters.
What does the Pentair GW9015 reducer cone do?
The GW9015 reducer cone connects and seals hose sections on compatible Pentair suction-side pool cleaners, maintaining proper vacuum pressure throughout the system. Manufactured by Pentair, it’s molded to precise tolerances so hoses seat firmly without slipping or drawing air. Replacing a worn or loose reducer cone restores optimal cleaner performance and prevents frustrating suction loss.

Expert Comparison & Pro Tips
Aftermarket hose adapters may look similar, but slight variations in diameter can cause minor air gaps that compromise vacuum pressure. The GW9015 is engineered to Pentair’s original specifications, which ensures proper compression and long-term reliability. In field service, loose hose fittings account for many “weak cleaner” complaints that are easily solved with the correct reducer cone.
Pro Tip: When replacing the reducer cone, inspect all hose connections and swivels for cracks or wear. Even a small split in the hose cuff can reduce overall suction and impact cleaning performance.
