So for a/c trinary switch replacement, the whole pipe assy is only option?

Yeah unfortunately you have to buy the whole assembly (hi pressure line from condenser to receiver. Appx cost is about 150 :(

Superduper & leeme guess, the oring on new trinary switch, still has to be changed to green r134 oring.

I don't know about that. Don't see why the new o ring can'tj be used.

Please note that Subaru only sells a new trinary switch as a complete unit (high pressure pipe). You mentioned your problem is a leak, not a malfunctioning trinary switch. Perhaps simply installing a new o-ring would solve your issue. If however, your trinary switch is malfunctioning I have a used one (not sure of it's working condition but maybe worth a shot). There may be an aftermarket option too...
