Pentair 521147 Intellichlor Gasket Kit 10 Pack

A salt cell that weeps a fine white crust at the union threads usually points to a hardened O-ring rather than a cracked cell.

• 10-pack cell union O-rings for Pentair IntelliChlor IC15, IC20, IC40, IC60, and iChlor generators
• Seals the cell union fittings (part 520595) on each end of the cell
• Also used in the 520670 acid washing kit plug

Replace both union O-rings at the same time even if only one side is leaking. They wear on the same schedule.
