About this hardware/other

The Sloan Compression Nut 400587 is a precision-engineered replacement component designed for Sloan LED lighting systems in residential and commercial spas.

Common symptoms this part fixes

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

  • LED light fixture leaking water into the spa shell
  • Light assembly won't seat or seal properly
  • Loose or wobbling light fixture in the niche
  • Stripped or cracked compression nut causing water infiltration
  • Light fixture backing out under water pressure

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

Before you buy — quick checklist

  • Confirm your existing nut is Sloan OEM part 400587 — cross-referencing by thread spec alone is not sufficient
  • Verify the 3/8-16 thread pitch matches your existing light assembly before ordering
  • Inspect the light niche and fixture body for cracking or damage — a new nut won't fix a damaged niche
  • Check whether the o-ring or gasket on the light assembly also needs replacement before reinstalling
  • Turn off all power to the spa at the breaker before disassembling any lighting components

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