Brake question -an to wheel clylinder

If I want to adapt -an fittings to my brake system, what sizes would fit ford wheel cylinder, (1975 drums) to -an size?

 

What size is the fitting on a ready made steel brake line? Is it 3/8 x 24 ?

 

On 3/16" tubing, yes.

 

Thank you

 

I must be dense, I want to adapt -3AN female to my ford brakes. The ford is 3/8 x 24. I can only find -3AN couplers that adapt 1/8, 1/4" pipe. No -3AN to 3/8. What am I missing?6

 

Hi FS;
Look at Speedway #910-318, or #617-4396. This should go into your wheel cylinder (if I understand what you are trying to do), and allow you to attach AN #3 or #4 tubing.

 

Her's some if I understand your need:

I don't think anyone makes/offers a 3/8-24 male to AN-3 female fitting. Why won't a double male work?
