About this seal/gasket

The Sloan O-Ring 400417 is a precision light lens seal designed for Sloan spa lighting systems. This OEM replacement O-ring maintains the watertight seal between your spa light lens and housing, preventing water infiltration that can damage electrical components. With dimensions of .364" inner diameter and .070" outer diameter, this rubber seal ensures your underwater lighting operates safely and reliably.

At Bubbles Supply, we stock genuine Sloan parts with exact fit guaranteed and same-day shipping on most orders. This O-ring comes with our standard 1-year warranty for peace of mind. When replacing your spa light lens O-ring, clean the groove thoroughly and apply a thin layer of silicone lubricant for proper seating and extended seal life.
