I don't have the flex hose with me right now, but it's a standard gray flex hose for a wet/dry filter 1 1/4" ID to fit 1" pvc. I found an adapter for the hose that steps it up to 1 1/2 but it has MPT. So all I need now is an adapter with 1 1/2 FPT to 1 1/2 slip fit. Does anyone know if they make one?
