Pentair Drain Cap Gasket | Clean & Clear / Predator Cartridge Filter | 86300500

The Pentair Drain Cap Gasket (86300500) is the OEM replacement gasket for the drain cap on Pentair Clean & Clear, Clean & Clear Plus, and Predator cartridge filter systems manufactured before November 1998.

⚠️ IMPORTANT: PRE-NOVEMBER 1998 FILTERS ONLY
This gasket is designed for Clean & Clear, Clean & Clear Plus, and Predator filters manufactured before 11/98. If your filter was manufactured after November 1998, this part may not be correct for your unit. Verify the manufacture date on your filter's label before ordering.

The drain cap gasket seals the drain port at the base of the filter tank, preventing water from bypassing the drain cap during normal operation. A deteriorated or missing gasket allows water to weep from the drain fitting, which can be mistaken for a cracked tank or loose plumbing connection. Replacing this gasket restores a watertight seal at the drain port. Match the part number on your existing gasket or confirm your filter's manufacture date before ordering.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Check your filter's manufacture date label — typically found on the tank body or data plate — before ordering. This gasket is correct for units built before November 1998. While the drain cap is off, inspect the drain cap threads and the seating surface on the tank for any cracking or corrosion that could prevent a proper seal even with a new gasket in place.
