Product details

Pentair 154747 is the spacer washer used in PacFab Nautilus and Nautilus Plus DE filters. It is the genuine Pentair part, and Pentair notes it may fit other Pentair model filters as well.

What a spacer washer does

Unlike a sealing washer, a spacer sets and holds a distance inside an assembly. Get the thickness wrong and parts either bind or sit loose, so the part number matters more than the outside dimensions. Order 154747 rather than matching a washer by eye.

When to order it

Usually alongside a filter strip down, when the internals are already out and the old washer is found cracked, deformed or missing. Small hardware like this disappears easily during a service, so a spare in the box is cheap protection against a half finished job.

Questions and answers

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

Which filters does it fit?
Pentair PacFab Nautilus DE and Nautilus Plus DE filters. Pentair notes it may fit other Pentair model filters as well.
Is it a genuine Pentair part?
Yes. It is Pentair part 154747.
Can I substitute a generic washer?
Order by part number. A spacer washer sets a specific gap in the assembly, and a similar looking washer of the wrong thickness will not hold it.
Should I order more than one?
Check your parts diagram for how many the assembly calls for, and consider a spare since small parts are easy to lose during a filter strip.
