About This Item
The Pentair Stainless Steel Flat Washer (072173) is the OEM replacement 5/16 in. stainless steel flat washer for the Pentair Challenger High Flow pump series.
What It Does
This flat washer distributes fastener load across the mating surface during pump assembly, preventing fastener pull-through and protecting the integrity of the pump's mechanical connections. Replacing worn or corroded washers at service intervals maintains proper clamping force and prevents hardware failure in wet pool equipment environments.

Pro Tip
When servicing your Challenger High Flow pump, inspect all hardware for corrosion at the same time. Stainless steel washers in pool environments can still develop surface rust or deformation under sustained clamping load — if the original washer shows any pitting, deformation, or discoloration, replace it as a matter of course. Order the quantity you need for all fastener positions being serviced in a single visit.
