About this seal/gasket

The US Seal PS-3867 is a premium Viton pump seal engineered for salt water and ozone sanitizer systems. This OEM-quality seal fits pumps with 5/8" shafts and features a 1.218" outer diameter, specifically designed to withstand the harsh chemical environment of modern spa sanitization systems.

Built with Viton material for superior chemical resistance, this seal delivers reliable performance in salt water generators and ozone-equipped spas where standard seals fail prematurely. At Bubbles Supply, we guarantee an exact fit with our comprehensive quality control, plus same-day shipping and a full 1-year warranty for your peace of mind. Professional installation recommended - verify your pump's shaft diameter and seal housing measurements before ordering to ensure 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 pump shaft area
  • Seal failure causing water intrusion into motor bearings
  • Premature seal wear in saltwater or ozone systems
  • Visible weeping or dripping at pump mid-section
  • Chemical corrosion destroying standard rubber seal

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

Before you buy — quick checklist

  • Confirm your pump shaft diameter is exactly 5/8" before ordering
  • Measure your existing seal's outer diameter to verify 1.218" match
  • Identify whether your spa uses a salt water generator or ozone system — Viton is critical for these applications
  • Standard EPDM or buna seals are not interchangeable with this Viton seal
  • Inspect motor bearing for water damage before installing — a failed seal may have already allowed water ingress

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