About this seal/gasket

This 5" ID x 5-1/4" OD O-Ring (805-0248) is an OEM Waterway replacement seal designed for SpaFlo Series pump volutes. This precision-engineered rubber gasket creates a watertight seal between pump housing components, preventing leaks and maintaining optimal water circulation in your spa system.

Built to Waterway's exacting specifications, this O-ring delivers the exact fit guaranteed performance you need to restore your pump's reliability. We ship same-day from our Canadian warehouse and back every part with our comprehensive 1-year warranty for complete peace of mind. Before installation, clean all sealing surfaces thoroughly and apply a thin layer of silicone lubricant to ensure proper seating and extend seal life.

Before you buy — quick checklist

  • Measure your existing o-ring ID and OD before ordering — confirm 5" ID x 5-1/4" OD
  • Verify your pump is a Waterway SpaFlo Series model
  • Inspect the o-ring groove for cracks, corrosion, or debris that could prevent a proper seal
  • Have silicone-based lubricant on hand — do not use petroleum-based lube on rubber o-rings
  • Shut off power to the spa at the breaker before disassembling the pump

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