Appears to actually be for 1-1/2 in pipe
the opening on these rubber couplers is around 1-5/8 inch which would make sized for a pipe with an OD of 1-1/2 inch as opposed to the 1-1/4 inch it is labeled for. additionally, the valve doesn't make a tight enough seal to stop water from slowly leaking through it.
Response from Superior PumpJun 25, 2020
Hello! The 1 1/4" measurement is the inside diameter of the valve. If the valve is not making a tight enough seal, you want to use the hose clamps provided to tighten that connection. If you need further assistance, please call our helpline at 1-800-495-9278 and we would be happy to help! Thank you!
