Description

The Aladdin O-13-9 is an o-ring for the 756 Series filter lid, also listed under the number U9-046.

What it does

The o-ring seats between the lid and the filter body, sealing the connection so the filter tank holds pressure and does not leak at the lid.

Fit and compatibility

This o-ring is sized for the 756 Series filter lid. Compare it to your current o-ring before ordering to confirm the fit, since lid o-rings for other filter series are not the same size.

Before you order

Replace the lid o-ring if it is flattened, cracked, or no longer seals tightly, since a worn o-ring is a common cause of a leaking filter lid. A light coat of o-ring lubricant on installation helps the lid seat evenly and makes the next removal much easier on the threads down the road.
