Spa Pump Inflation Nuts (A Coupling)
Replacement Coupling for all Lay-Z-Spa models.
If the Coupling supplied with your Lay-Z-Spa is lost or damaged, this Coupling can be purchased as a direct replacement.
The Coupling is used to secure the pipe on the heater pump to your Lay-Z-Spa liner. The pipe is used to inflate the liner via the heater pump. It also creates the relaxing bubbles in your spa. If you don't have a Coupling, you'll be unable to secure the pipe to the liner and inflate it with the heater pump. You'll also be unable to operate the massage system.
Compatible with all Lay-Z-Spa models
