The Pentair Hinged Weir Assembly (08650-0022) is the OEM replacement weir door for the Sta-Rite U-3 skimmer. This part is also referenced in service documentation as fitting Swimquip U-3 skimmers. Available in White or Gray (C).
IMPORTANT: LEGACY BRAND — STA-RITE / SWIMQUIP
This part is sold under the Pentair catalog as a Sta-Rite component. The U-3 skimmer was also marketed under the Swimquip name. If your skimmer lid, body, or service label reads "Swimquip U-3" or "Sta-Rite U-3," this is the correct weir assembly for your unit.
The weir door is the hinged flap seated at the skimmer throat. It swings inward to allow surface water and debris to pass into the skimmer basket, then returns to block reverse flow when the pump shuts off — preventing collected debris from washing back into the pool. A damaged, warped, or missing weir reduces skimming efficiency and allows debris to re-enter the water. This replacement restores the correct fit and pivot action for the U-3 skimmer opening.

Pro Tip
The U-3 skimmer has been produced over many years and minor dimensional revisions can exist between production runs. If the part number is still legible on your existing weir — typically molded into the back face of the flap — match it directly to 08650-0022 before adding to cart.
