Unions for IntelliChlor Salt Cell 520595

Two Unions Per Pack — Not a Replacement Cell

This listing is the Pentair 520595 union kit for IntelliChlor salt cells. The Amazon listing specifies “2 unions” in the pack, and its item data shows two items per order.

When this is the part you need

Unions are the threaded collars that bolt the salt cell into your plumbing. They’re typically replaced when threads strip or a fitting leaks — not as a routine companion to every cell replacement. Because two unions ship in one kit, a single order covers both sides of the cell.

Check before ordering

• Confirm your system is an IntelliChlor salt chlorinator and that the fittings — not the cell — are the problem.
• Match the part number on your existing union kit to 520595.
