Jandy O-Ring for TruClear Cell

The Jandy R0694100 is the genuine o-ring for the cell on the Jandy Pro Series TruClear chlorine generating system. It is a Zodiac part, listed under both the Jandy and Zodiac names.

When to replace it

Replace the o-ring whenever the TruClear cell is removed for acid cleaning or swapped for a new one, and right away if the cell connection begins to weep. An o-ring that has been compressed for a season takes a set and seldom seals reliably once it has been disturbed, and a slow drip at the cell is the kind of leak that goes unnoticed until the pad is wet.

Installing it

Clean the groove, coat the new o-ring lightly with a silicone based lubricant, and seat it evenly before tightening the cell. Keep a spare on hand so the next cleaning does not wait on a part.
