About this seal/gasket

This Waterway 2" ID x 2-1/4" OD O-Ring (805-0226) provides a critical watertight seal for 1-1/2" spa unions in your hot tub's plumbing system. The precision-molded rubber gasket features exact 2" inner diameter, 2-1/4" outer diameter, and 1/8" cross-section dimensions to ensure proper compression and long-lasting performance in union connections throughout your spa's circulation system.

As an OEM Waterway component, this o-ring delivers the exact fit guaranteed quality you need to prevent costly leaks and maintain optimal water flow. We ship same-day from our Canadian warehouse and back every part with a full 1-year warranty for complete peace of mind. When replacing union o-rings, always inspect the union surfaces for scratches or debris that could compromise the seal, and apply a thin layer of silicone lubricant for easier installation and enhanced sealing performance.

Common symptoms this part fixes

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

  • Slow drip or steady leak at a union connection
  • Water pooling under the spa equipment bay
  • Loss of prime due to air infiltration at union joint
  • Visible cracking, flattening, or extrusion of the existing o-ring
  • Leaking union after recent plumbing work or pump service

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

Before you buy — quick checklist

  • Measure your existing o-ring — confirm 2" ID, 2-1/4" OD, and 1/8" cross-section before ordering
  • Verify your unions are Waterway brand — o-ring dimensions can vary by manufacturer even on same nominal pipe size
  • Inspect union mating surfaces for scoring, cracks, or mineral buildup that would prevent a proper seal even with a new o-ring
  • Check whether the union body or nut is also damaged — a new o-ring won't fix a warped or cracked union housing
  • Have silicone lubricant on hand before you start — do not use petroleum-based lubricants on rubber o-rings

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