1-1/2" heater or pump union gasket which is flat on both sides.
Gaskets are always measured by the internal diameter size of the pipe the fitting is connected to - really confusing when nothing measures what it says.
To help, the outside diameter of these is 2-3/8"
Every hot tub part is measured in inches.
