I originally bought a set of R134a sensors before my air conditioner failed. It was too difficult to convert anything with R410a. I bought this kit that works with R22, R410a and R134a and I really like it. The extra port allows you to pump down and charge the lines at the same time without changing lines. I really love this set. The old set went to my son.
