Don't know if that uses the same inner parts as the one in a combo valve. There were a lot of problems with the aftermarket ones a couple years ago (including Inline Tube) Don't know if that has been resolved. I rebuilt my combo combining used parts from 2 valves. If you get a used one, I would advise opening and clean/inspect. They build up sludge. Just use a lot of care to get it all back together as it was. And there is a spring in there...
