My high side port is leaking. Upon closer inspection it seems that it has a non replaceable valve. Is this the case? Is there any adapter that fits on the service fitting that will "adapt" or seal? Or is a new hose the only way?
If they stuck with the old fashion Scharder type valve, could screw in a new valve stem and would be like new again. That neoprene disk is rather large in a R-134a port, gets dry and brittle and doesn't seat properly. This was approved by the EPA at the request of the automakers to make it easier for them to use a quick coupler for production. Never gave leakage a concern. If not leaking to bad, would be nice to find a metal valve cap with a good neoprene seal. Ones today are cheap plastic that easily break if tightened too much.
Yeah, I know, we all know, its a pain in the butt and expensive. R-134a port leakage is a common problem from an agency that will fine you $25,000.00 if you released an half an ounce of R-134a, but they let stuff like this get by. A bunch of hypocritical idiots.
If it is made with Ford parts, the high side port assembly should be replaceable by unscrewing it from the part welded to the line. System must be emptied to do that of course.
35-50021 Primary Valve
The part you linked to :35-50021 is designed to screw onto an existing pipe with a threaded piece welded to it? The part I have would need would have to be cut and welded with a schrader type valve, I think. I guess I'm "hosed" ( no pun intended)
Upon closer inspection both high and low side valves are replaceable and have male threads with a small green O ring. Can you send a link with the correct part numbers?
