Pentair Flat Washer 1/4" x 5/8" for IntelliFlo Pumps | 072183Z

The Pentair Flat Washer (072183Z) is the OEM replacement 1/4" ID x 5/8" OD hardware washer used on IntelliFlo variable speed pump assemblies, including the IntelliFlo VS, VS+SVRS, and i1/i2 models.

IMPORTANT: 2 WASHERS REQUIRED PER PUMP
This listing is sold as Qty 2. Two washers are required per pump assembly — verify you are ordering enough for your complete repair before checkout.

IMPORTANT: VERSION-SPECIFIC FITMENT — CONFIRM YOUR PUMP'S BUILD DATE
This washer fits IntelliFlo i1 and i2 pumps built after April 2016, and IntelliFlo VS+SVRS pumps built after June 2016. Check your pump's manufacture date before ordering to confirm fitment.

This flat washer provides a flat, even bearing surface for hardware fasteners on the pump housing, preventing localized stress or loosening at the fastener point during normal pump vibration and operation.

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

Because fitment on this washer depends on your pump's production date, check the data label on your IntelliFlo pump housing before ordering — i1/i2 and VS+SVRS models built before the noted 2016 cutoffs used a different fastener configuration. If you're already replacing this washer during a seal or housing service, it's a good time to inspect the surrounding fasteners for corrosion, since stainless hardware in wet pump environments can still develop surface pitting over time.
