"this is just the male adapter. anyone know where i can get a full replacement valve?"
There is a female component? I don't have a thermarest pad to look at, by my understanding was that the male component was just bonded ("potted") into the seam. I've used these replacement valves to make MYOG inflatable sleeping pads, and I just bonded them into the seam. Bender (of now-defunct Kookabay) made all of his early pads this way, I think.
I'm actually stuck at the valve-selection stage of a MYOG inflatable sleeping pad project right now. More recently I've used Airtime kite bladder valves instead of Thermarest replacement valves because the kite valves are soft (less strain on surrounding fabric) and seem more durable. But the kite valves are bulky. I haven't found a commercially available alternative that is any better, though. So I'm making plans to fabricate my own valve. It will be time consuming, but I don't know any other way.
I once found an old inflatable sleeping pad from the 1980s at a garage sale that had two valves that were just like Exped's valves: flat and rubbery. They were perfect. I bought the pad for $1, cut the valves out, and used them for an MYOG pad that I later gave to a friend. I wish I could find more like those.
