"chinese" 1 1/4 inch barbed coupler (Harbor Freight - Drummond sump hose)

This is not a true 1 1/4 inch. This is what the chinese use for 1 1/4 inch which ends up being ~11% smaller than true 1 1/4 inch.

I made this because Harbor Freight's DRUMMOND 1-1/4 in. x 24 ft. Sump Pump Discharge Hose Kit cannot use a normal 1 1/4 inch barbed coupler. This may work on other products produced by chinese companies.
