Also fits the master power combo valve that I use have. Took a chance and it worked since master power wants way too much for a single one.

I was trying to find the tool for a proportioning valve in a Ford vehicle, thought I would take a chance on these but they were too large. It seems all are listed for PV2 and PV4 valves, I could not find a thread size to help me make sure it would fit.
