A/C High Side Port

It is clear in the pictures that a schrader valve would not fit (inner diameters are different, as well as no threads).

But I dug it out of the trash, pulled the rubber out with a pick, and took a picture of the plunger that keeps the rubber in place. Definitely a different style valve, and non-serviceable (only replaceable).

Interesting. I never even noticed the difference when I did mine so I didn’t look into it. But 3 years so far, ac blows super cold. Before I replaced both, the charge lasted at best one summer.
