About this seal/gasket

This Waterway 2-3/4" ID x 3" OD O-Ring (part #805-0232) creates a watertight seal for union connections in your spa's plumbing system. Designed for 2-1/2" union fittings, this OEM replacement part prevents leaks where pipe sections connect, ensuring your spa operates efficiently without water loss or air infiltration.

At Bubbles Supply, we guarantee this O-ring delivers an exact fit for your Waterway union assembly, backed by our 1-year warranty and same-day shipping commitment. The precise 2-3/4" inner diameter and 3" outer diameter specifications ensure proper compression and sealing performance. Before installation, clean the union groove thoroughly and apply a thin layer of silicone lubricant to prevent pinching during assembly.

Common symptoms this part fixes

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

  • Air bubbles in return jets (air infiltration at union)
  • Pool of water forming under equipment pad
  • Spa losing water overnight with no visible crack

Before you buy — quick checklist

  • Measure your existing o-ring ID and OD before ordering — 2-3/4" ID x 3" OD is specific to 2-1/2" Waterway union fittings
  • Confirm your union is a Waterway brand fitting — o-ring dimensions vary by manufacturer
  • Inspect the union groove for cracks, gouges, or debris that could cause a new o-ring to fail immediately
  • Check whether the union body itself is damaged — an o-ring won't fix a cracked union collar
  • Have silicone lubricant on hand before starting; do not use petroleum-based grease

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