About this seal/gasket

The Sloan O-Ring 400510 is a clear silicone LED seal designed for Sloan spa lighting systems. This precision-engineered gasket features a .362" inner diameter and .103" cross-section, providing reliable waterproofing for LED light assemblies in hot tubs and spas. The clear silicone construction ensures optimal light transmission while maintaining a watertight seal in high-temperature spa environments.

At Bubbles Supply, we guarantee this OEM Sloan O-Ring delivers exact fit performance with our same-day shipping and comprehensive 1-year warranty. The durable silicone material resists spa chemicals and temperature extremes, ensuring long-lasting protection for your lighting system. Always verify your existing O-ring dimensions match the .362" ID x .103" CS specifications before installation to ensure proper sealing and optimal LED performance.

Before you buy — quick checklist

  • Measure your existing O-ring — confirm .362" inner diameter and .103" cross-section before ordering
  • Verify your spa uses a Sloan LED lighting system — this is an OEM-specific seal
  • Inspect the light housing seat for cracks or damage that could prevent a new O-ring from sealing properly
  • Check whether the light assembly requires full removal to access the O-ring or if it can be replaced in place

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