I just completed my removal of the ABS system and I am having problems finding the needed fittings in Japanese/metric thread. They are 3/16th lines I am using to run the custom rounting. I wantd to add a proportioning valve just in case its needed but the only valves I can find so far use standard thread. Anyone know a good source for metric thread fittings such as unions or 1 into 2 brass block splitters? I need to find splitters and fittings for the proportioning valve.
