Quick Product Summary
The Jandy R0621900 is the installation, pressurizing, and winterizing cap used with Jandy TruClear chlorine generating systems. It installs in place of the TruClear salt cell when the cell is removed for winterizing, cleaning, maintenance, or applicable service procedures. Jandy specifically identifies R0621900 as the TruClear cap that can replace the cell during winterizing or cell maintenance so the pool pump can continue circulating water with the cell out of the line.
Best For
- Jandy TruClear salt chlorinator owners preparing the system for winter conditions.
- Pool professionals removing the TruClear cell for cleaning, inspection, or maintenance.
- Service procedures that require the TruClear cell to be temporarily removed from the plumbing line.
- Replacing a missing or damaged R0621900 cap.
Why This Matters
- Leaving the correct cap available makes seasonal winterizing and cell service easier.
- The cap provides a temporary replacement for the cell position instead of leaving the TruClear housing open.
- Jandy states that the pump can circulate water with the cell removed when the winterizing cap is installed.
- Using the exact R0621900 part number helps avoid ordering a cap intended for a different salt system.
Common Signs You Need This / Use This When
- You are removing the TruClear cell for winter storage.
- The salt cell needs to be removed for cleaning, inspection, or maintenance.
- Your original TruClear winterizing cap is missing or damaged.

Compatibility / Fitment Notes
R0621900 is specifically identified by Jandy for the TruClear chlorine generating system. Do not assume it fits other Jandy, Zodiac, or third-party salt chlorination systems simply because the cap looks similar. Match the system name and part number before ordering.
Installation / Use Notes
Turn off the circulation system and follow the current Jandy TruClear manual before removing the cell or opening the plumbing system. Install R0621900 only as directed for winterizing, cell maintenance, installation, or applicable service procedures. If the cap is being used as part of a pressure-testing procedure, follow Jandy's current pressure-testing safety instructions and limits. Reinstall the TruClear cell correctly before returning the chlorination system to normal operation.
