Aladdin Stand Pipe O-Ring For Pentair FNS Plus & CCP Filters | 154492 | O-83

Engineered as a direct aftermarket replacement for Pentair part number 154492 , the Aladdin O-83 is the 2-inch bulkhead standpipe O-ring used in Pentair FNS Plus and Titan/Titan CM D.E. filter series. The O-ring seats at the filter's internal bulkhead standpipe connection and forms the watertight seal that prevents water and D.E. powder from bypassing the filter grid assembly and leaking internally — a function that becomes critical because a degraded or flattened bulkhead O-ring is one of the most common causes of D.E. powder returning to the pool after backwashing. The O-83 measures approximately 2-3/16 inches inside diameter, slightly under 2-1/2 inches outside diameter, and just over 3/32 inches in thickness, matching OEM dimensions precisely for a leak-free fit at the bulkhead. The O-ring also cross-references Jandy/Zodiac part number R0792000, extending its usability to additional Jandy filter platforms.

Highlights

• Pentair 154492  Dimensional Match: Aladdin engineers the O-83 to match the exact dimensions of the Pentair 154492 bulkhead standpipe O-ring, with a roughly 2-3/16 inch inside diameter, just under 2-1/2 inch outside diameter, and slightly over 3/32 inch thickness, providing a precise, properly seated fit in Pentair FNS Plus and Titan/Titan CM D.E. filters during routine seal service.
• Addresses D.E. Powder Blow-Back: When the bulkhead O-ring is worn or compressed, water can bypass the filter grid assembly and carry D.E. powder back into the pool after every backwash cycle, and replacing the seal with a fresh O-83 restores the proper internal sealing surface and eliminates this common visible filtration complaint.
• Compatibility with Jandy R0792000: The O-83 is also confirmed as a cross-reference replacement for Jandy/Zodiac part number R0792000, which adds compatibility with select Jandy CL and DEV Series cartridge and D.E. filter models including the CL460, CL580, and DEV48, giving service professionals a single O-ring that covers both Pentair and select Jandy platforms.
• Budget-Friendly OEM-Equivalent Performance: As an aftermarket replacement, the Aladdin O-83 provides OEM-equivalent sealing performance at a meaningfully lower price point than the factory Pentair 154492 part, making it an efficient, budget-conscious option for stocking routine filter seal replacements across multiple pool service accounts.
• Pool-Grade EPDM Rubber Build: The O-ring is molded from pool-grade EPDM rubber chosen for its ability to resist continuous chlorinated and salted pool water exposure, ongoing internal water pressure, and seasonal temperature variation, keeping the seal elastic and dimensionally stable rather than allowing it to harden or take a permanent set over time.
