About this seal/gasket

The US Seal PS-1000 is a precision-engineered pump seal designed for spa circulation and jet pumps with 5/8" shafts. This OEM-quality seal features a 1.437" seal outer diameter and 1.250" seat outer diameter, making it compatible with various spa pump models that require these exact specifications.

Built to professional standards, this pump seal ensures reliable operation and prevents costly water leaks. At Bubbles Supply, we guarantee an exact fit for your pump application and back every seal with our comprehensive 1-year warranty. Most orders ship the same day for minimal downtime. Verify your pump's shaft diameter and seal dimensions before ordering to ensure proper fitment – incorrect seal sizing can lead to premature failure and water damage.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Water leaking from underneath the pump
  • Wet end dripping around the motor shaft
  • Seal face worn or scored causing visible seepage
  • Mineral buildup around the shaft indicating slow seal failure
  • Pump running dry due to seal bypass

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your pump shaft diameter is exactly 5/8" — this seal will not fit 1/2" or 3/4" shaft pumps
  • Verify seal outer diameter is 1.437" and seat outer diameter is 1.250" against your existing seal before ordering
  • Inspect the seal seat and impeller housing for scoring or cracks — a damaged seat requires replacement alongside the seal
  • Drain and disconnect the pump completely before attempting seal replacement
  • Have a seal puller or flat-blade tool ready — the old seal may be pressed in tightly and require careful extraction

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
