Exactly what I needed
I bought 2 reducers for my upper and lower radiator hose. They were easy to install and fit/work perfectly.

Used
Used great deal!! Came with no issues But wrong size for what I needed. Diameter is to big OD is 1-1/2 needed to fit inside of a 1-1/2 pipe not enough material to hog down to make work... But will not go to waist. Only negative thing, is the images show there is more material then there actually is.

Don’t be afraid to experiment or ask questions.
I had to replace the radiator on my el Camino with an aftermarket unit because the original replacement was so expensive. But the radiator inlet and outlet were the same size ( 1 1/2” ) So I used this reducer to change the upper outlet back to 1 1/4”.
