Poolrite Enduro / Spaflow Pump Lid O-Ring & V2000 MPV 40mm Top Gasket (POV-601-91018)

Genuine replacement Poolrite Enduro / Supaflow / Spaflow Pump Lid O-Ring — SKU POV-601-91018. This 40mm rubber O-ring serves a dual purpose: it seals the pump lid on Poolrite Enduro EP550, EP750, EP930 and EP1100 pumps, as well as Poolrite Supaflow and Spaflow pumps, and also functions as the top gasket on the Poolrite V2000 multiport valve (MPV). A worn or cracked O-ring causes water to leak from around the pump lid or valve top. Replacing it restores a watertight seal.

Frequently Asked Questions

Does this O-ring suit both the pump lid and the V2000 MPV?

Yes — part POV-601-91018 is the correct O-ring for the Poolrite Enduro EP550, EP750, EP930 and EP1100 pump lids, Poolrite Supaflow and Spaflow pump lids, and the Poolrite V2000 multiport valve top gasket. The same 40mm O-ring is used in both applications.

How do I know if this O-ring needs replacing?

On the pump: if water is leaking from around the pump lid on your Enduro, Supaflow or Spaflow pump, or if you notice air bubbles in the pump basket, the lid O-ring is the most likely cause. On the V2000 MPV: if water is leaking from the top of the multiport valve, the top gasket O-ring is the likely cause. In both cases, turn off the pump, relieve system pressure, remove the lid or valve cover, and inspect the O-ring for cracks, flattening, or deformation.

Should I lubricate the O-ring when fitting it?

Yes — apply a small amount of silicone-based O-ring lubricant (not petroleum-based grease) to the O-ring before fitting. This helps it seat correctly, prevents pinching during assembly, and extends its service life.
