What size threads are on the brake lines to the proportioning valve?

["Turbo-T"]

This is what my proportioning valve looks like. It's the brass style.

I am in the middle of installing my Biondo line lock to meet NHRA specs, meaning I'll be running a line off the proportioning valve into the line lock and then on to the front brakes.

I want to retain my stock brake line fittings at the proportioning valve in case I ever want to put it back original. (meaning no more line lock) However the fittings do not fit the brass fittings I was told here to purchase.

The tee inverted flare, 130333, which I was told to get, does not allow either of stock line fittings for the front brakes off of the proportioning valve. Also the pipe plug I was told to get, p/n 120300 when screwed in to the proportioning valve, allows brake fluid to leak.

All of the brass fittings I purchased are the Edellmann fittings.

So does anyone know what size/thread count are the fittings that screw into the proportioning valve, that go to the left and right front calipers?

Thanks in advance.

The inlets to the combo, from the master are:

Front: 1/2"-20
Rear: 7/16"-24

The outlets from the combo to the brakes are:

Front: 3/8"-24 (two places)
Rear: ??

I never measured the rear outlet, so I don't know what that one is.

{edit: these fittings are inverted flair, typical for brake usage}


The 130333 T should be 3/8"-24 thread. Edelmann lists it as 3/16" tube size.
