About this seal/gasket

This LX pump seal is designed specifically for LX 48 and 56 frame pumps, providing a critical watertight seal between pump components. The SEAL-56WUA fits both 48WUA and 56WUA pump models, making it a versatile replacement part for many LX spa circulation systems.

Manufactured to OEM specifications, this seal delivers exact fit guaranteed performance and comes with our 1-year warranty for complete peace of mind. We ship same-day from our Canadian warehouse, getting your spa back up and running fast. The seal prevents water leakage that can damage pump motors and reduce efficiency. Ensure your pump is completely drained before installation, and verify your pump's frame size matches either 48 or 56 configuration for proper fitment.

Common symptoms this part fixes

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

  • Water leaking from the front of the pump housing
  • Wet motor casing or corrosion around motor shaft
  • Pump runs but drips continuously at the impeller housing
  • Visible water pooling beneath the pump during operation
  • Premature motor failure caused by seal-related water intrusion

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

Before you buy — quick checklist

  • Confirm your pump model is either 48WUA or 56WUA — check the label on the motor housing
  • Determine whether the leak is originating from the shaft seal area (front of pump) vs. plumbing fittings
  • Inspect the impeller and volute for cracks before ordering — a failed seal can sometimes be a symptom of a bigger issue
  • Drain the pump and wet end completely before disassembly
  • Have snap-ring pliers and seal puller tools on hand before starting — this job requires them

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