About This Item

The Pentair Bulkhead Union Set (98960311) is the OEM replacement bulkhead union set for the Clean & Clear Plus cartridge filter series.

IMPORTANT: SET INCLUDES BOTH BULKHEAD UNIONS
This listing is sold as a complete set. One set includes both the inlet and outlet bulkhead unions required for your filter.

IMPORTANT: PRE-NOVEMBER 1998 FILTERS ONLY
This bulkhead union set fits Clean & Clear Plus filters manufactured before November 1998. Filters produced after that date use a different union design and are not compatible with this set. Check the manufacture date label on your filter tank before ordering.

The bulkhead union set provides the threaded plumbing connection points between your filter tank and the pool's circulation plumbing. A failed or cracked bulkhead union causes water loss at the filter and prevents proper system pressure. Replacing the complete set restores a leak-free, pressure-rated connection.

Poolaroo Pro Tip

When replacing bulkhead unions on an older Clean & Clear Plus filter, inspect the tank's bulkhead port threads and the surrounding housing for hairline cracks before installing the new set. Stress fractures around the port openings are common on filters of this vintage and will continue to leak even with new unions installed. If the port area shows damage, the filter tank itself may need replacement rather than just the unions.
