Does anyone know what the thread size is on the flare nuts that go from the valve body to the rack on a 3dr cosworth, by thread size i mean the thread pitch i.e. 10 x 1 mm also what the maximum working pressure of the system is thanks.

 

Is the 3 door different to the Sapphire ? What's the valve body ?

Working pressure would easily be in excess of 1000psi for PAS systems.

Most systems simply have a pump and rack.

 

The 2wd sapphire is most likely the same the valve body is part of the rack it is where the input shaft goes in from the column and has the two pips coming out that go too the main part of the rack it is these pips that i need to know the thread size for thanks kevin c.

 

The pipes are about 6mm OD, so I'd suspect thread size to be bigger than M10. Can look later though and try and measure

 

thanks that would be great 10mm was just a example

 

Well Ive looked, but not a lot of help. I tried to undo one and it didnt want to move. I'm not going to force it.

I can say the steel pipe is 1/4" OD, and the thread appears to be just over 10mm. So it definitely is NOT a metric fitting of any sort.
Spanner size would be about 11.2mm or close to 7/16" ( 11mm wont fit )

It probably is some sort of pipe thread as opposed to a standard screw thread

 

thanks for looking it is the thread size i need so i can get some stainless ones
