I have several PCV's that are marked as follows on the box:

Ventilation Valve (with Old AC Logo)
CV 455C
6421982

It has a threaded end, and port for the hose.

What does this fit/Applications?


Thanks in Advance.

It sounds like a PCV valve from a 283 by the description, 63 to 67.

That's what I thought at first too....but the threads are coarse not fine thread. Sorry I should have mentioned that.

If I recall the thread is 1/4 pipe thread.

Anyone have an old AC parts catalog?

Thanks,
