Description
The Pentair 192320 Upper Bulkhead O-Ring is engineered to provide a durable, leak-resistant seal at the top bulkhead connection of your pool filter. Molded from Buna-N 70 elastomer and sized #2-137 for 2-inch applications, this OEM part is designed to resist chlorine, pool chemicals, and repeated pressure cycles. It fits a range of Pentair filtration systems including Clean & Clear Plus, FNS, FNS Plus, and Nautilus series. When your upper bulkhead shows signs of leaking or degradation, this O-ring is a direct replacement to restore proper sealing and system efficiency.
Pro Tip
Lightly lubricate the O-ring with a silicone-based lubricant before installation to ease seating and reduce wear. Always inspect the bulkhead surface for scratches or debris before installing to ensure a tight seal.
Installation Tips
Depressurize the filter before servicing. Clean both the bulkhead housing and surfaces thoroughly. Apply light silicone lube to the O-ring. Do not overtighten — snug engagement is sufficient.
