Product overview
The Tank O-Ring, 11-3/4-Inch OD for Sherlock Filters is an aftermarket o-ring built to replace the original component in Aladdin filtration systems. In service it forms the static seal between two mating components under compression. Replacement is routine: rubber hardens, flattens and cracks with heat, chlorine and UV exposure, and a failed o-ring is the most common source of air leaks and drips. Ours is molded in EPDM rubber. This part is cross-referenced to 4 Aladdin OEM numbers — O-413, 47038047, 47038047R, 4666-05 — so buyers working from a number stamped on a failed component can confirm the match before ordering.
