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.
