In preparing to replace my dead compressor and likely convert to R134, I've removed all of my ac components (except the evap) so I can clean everything well and change out the seals. However, connected to the top of my receiver drier is, what's listed on the parts guide, as a coupler. When connected, you can easily blow through the connection. When disconnected it seals the 2 ends. At first, I thought it was a way to isolate the drier for servicing. Problem is there's no "coupler" on the other end. The FSM doesn't really describe this piece when servicing the AC.
So what does this really do? The reason is that there are several very small o-rings inside that did not come with my o-ring kit. The small plugs inside each coupler half come right out so I can put the fittings back together without them.
I plan to check a few local places for them and if I find them I'll replace them. But if it's going to be a struggle to find them, I'd rather ditch it.
