If you have an older car with R12 it won't work. There is no pin on either end of the hose to push the Schrader valve in when screwing it in, as you can see in my drawing. The description says it's for the R12 car system, but it clearly isn't. I wrote to the seller but received no reply. I'll just go back and try to find another set.
