About this seal/gasket

This 6-3/8" ID O-Ring (VOR-56WUA500) is an OEM replacement volute seal designed for LX spa pumps. This critical rubber gasket creates a watertight seal between the pump volute and wet end assembly, preventing leaks and maintaining proper hydraulic pressure in your spa circulation system.

Engineered to LX's exact specifications, this genuine O-ring ensures perfect fitment and reliable performance. We guarantee an exact fit for your LX pump configuration and back every part with our comprehensive 1-year warranty. Most orders ship same day from our Canadian warehouse, getting your spa back online fast. When installing, ensure the volute surfaces are clean and free of debris, and lightly lubricate the O-ring with silicone grease for proper seating and extended service life.

Before you buy — quick checklist

  • Measure your existing O-ring's inner diameter — confirm it is 6-3/8" ID before ordering
  • Inspect the volute mating surface for cracks, gouges, or corrosion that could prevent a proper seal even with a new O-ring
  • Confirm your pump is an LX brand unit — check the label on the motor housing
  • Note whether the leak is at the volute joint specifically, as a different O-ring or shaft seal may be responsible for leaks elsewhere on the pump

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