Product details
The Aladdin O-413-9 is a generic replacement tank o-ring measuring 11-3/4 inches on the outside diameter, 11-3/8 inches on the inside diameter and 3/16 of an inch thick. It is listed for Jacuzzi CFR 50, 75, 100 and 150 cartridge filters, the Jacuzzi Avalanche DE filter and Sherlock filters.
Crossover numbers
The same seal turns up in parts lists as O-413, 47038047, 47038047R, 4666-05 and 90-423-5380. If your filter manual or your old bag carries any of those numbers, this is the ring.
The failure it fixes
Tank seals flatten, harden and crack with time and chlorine. The result is a filter that seeps or sprays at the clamp band, usually right after a cartridge cleaning when the old ring gets disturbed. Replacing the seal, rather than tightening the band harder, is the fix.
Fitting tips
Clean the groove and the mating face before you set the new ring, and use a silicone o-ring lubricant. It seats more evenly and separates cleanly the next time the tank comes apart.
