AC pressure switch fit?

AC pressure switch fit?
93 Toyota PU, V6 auto w/factory air
I am converting to 134A and replacing the condenssor. I removed the old pressure switch and liquid line from the old evaporater and noticed that the mating surfaces on the switch and liquid lines do not look right?? I do not know if these parts are OE? The shoulder on the switch is larger than the recess in the liquid line. I know an O ring goes in there, but it sure don't look right? Any thoughts? Jim

It looks "okay" to me. A standard o-ring will be pancaked when the switch is tightened gently to the right torque, sealing. The o-ring sits inside the fitting, but the shoulder of the switch is just flat.
