Product details

The Aladdin O-462-9 is the diffuser ring for the Jacuzzi Magnum pump. It has a square section rather than the round profile of a normal o-ring, and it measures 3 inches across the outside, 2-3/4 inches across the inside, and 1/8 inch thick in both directions.

What the diffuser ring does

The diffuser caps the impeller and steers water into the volute. The ring seals the joint between the diffuser and the housing. When it hardens, flattens or splits, water short circuits back around the impeller instead of leaving through the discharge, and the pump moves less water for the same effort.

Fitting it

Take the old ring out, clean the groove properly and check the seat for scale before the new one goes in. Because the profile is square, it needs to sit flat in its groove all the way round. A round o-ring of the same diameter is not a substitute.

Questions and answers

What people ask about this product, answered by our pool techs.

What are the dimensions?
3 inch outside diameter, 2-3/4 inch inside diameter, 1/8 inch thick. The section is square, so it measures 1/8 inch both ways.
Can I use a round o-ring instead?
No. This is a square section ring and it seats in a groove cut for that profile. A round ring of the same diameter will not seal the same way.
Which pump is it for?
The Jacuzzi Magnum.
My old ring has a different number on the invoice, is this the same part?
Very likely. This part is cross referenced to several numbers, including 373291, 429628, 47-0232-54R, 5064-11, 608513, O-462, 35-105-1063 and 90-423-1462.
