Description
The Hayward Shaft O-Ring (ECX9611246PAK3) is the OEM replacement shaft O-ring for Perflex Extended-Cycle DE filters and Slide Valve Assemblies, sold as a convenient set of 3.
IMPORTANT: LUBRICATION REQUIRED SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.
This O-ring seals the shaft on Perflex DE filter bump assemblies and Slide Valve Assemblies, preventing bypass and maintaining system pressure. Replacing a worn or damaged shaft O-ring restores a proper seal and eliminates leaks at the shaft interface.

Poolaroo Pro Tip
A set of 3 gives you spares on hand for the next service interval shaft O-rings are a routine wear item and keeping extras in your equipment kit avoids a second order. Before installing, clean the shaft groove thoroughly and apply a thin coat of silicone-based lubricant to seat the O-ring evenly and extend its service life.
