I'm attempting to replace my existing proportioning valve with a new adjustable valve, but it has 5 connections which are all 1/8th inch NPT. I'm trying to come up with exactly what the ends of the various brake lines running into the old block are but not having much luck down at my Ace Hardware.

Anyone have info or specs on what these fittings are?

Thx,
George Lehmann

Since brake lines are a double flare fitting, I doubt that they are a NPT thread. Might need an adapter to go from the new valve to the brake thread.
