• Fits standard wall openings used with Navigator systems
• Compact form factor keeps installation quick
• Check and replace the O-ring or seal if worn to ensure a watertight fit

This part is built to match original equipment dimensions and function. Its white finish blends with typical pool wall fittings, and the item’s weight keeps it manageable during handling and installation.

What maintenance or checks are recommended after installing the replacement?
