Do the existing schrader valves need to be removed or will the valve in these fittings push down to open the old valves simultaneously?

The schrader valves needn't to be removed, and the valve in these fittings push down to open the old valves simultaneously.

The high side fitting is too big for my old port?

Same here. The 2 fittings are the same size and both fit the low pressure port. This kit does not work.

Can anyone tell me if the low side port fits a .375 inch threaded r12 port?

The high side fits perfectly but the low side is too big! Why is this not fitting? What is the resolution?

Does the valve push down the existing valve in the port when it’s screwed on? Or when r134a goes in?

R12 to R134A retro fit fittings connect to the thread for use with the valve, there is a removable schrader valves., fitted with a plastic protective cover cap
