Is your Lay Z Spa leaking from the air blower connection? This replacement non-return valve is a quick and affordable fix! Designed for the 'A' connector on most Lay Z Spa and Bestway air-jet and hydro-jet hot tubs (like Vegas, Miami, Monaco, Paris, and more), this flexible rubber/silicone valve creates a one-way seal to stop water and chemicals from flowing back into the blower. Installation is simple – just pop out the old valve and push this one in. No tools needed! It's resistant to heat, chlorine, and UV, so it holds up well in spa conditions. By preventing backflow, it protects your blower and keeps your spa running smoothly. A must-have spare for any hot tub owner dealing with leaks or preparing for seasonal maintenance.
