There are a variety of fittings needed, depending on what you're plumbing up
From left to right:
These are Brass and Rubbish, stay away from these (Local suppliers seem to only be able to offer them),
Next, these are the original Oz Style ones as found in the rear subframe,
Next are the same as previous, but new from the UK,
Next is the M10 type for the Tandem M/Cs and
Last is the 3/8 UNF ones that cover most of the car.
This is the double flare, usually used with the M10 and the 3/8 Tube nut (last two on the right above)
Generally fitted in to something like this
This is an Invert Flare, as used with the hoses on the rear trailing arm, the Female Tube Nuts (first 3 from left above) are used with these
Fitted on to these
First part of making the lines is to make a mok up. I do this with steel welding wire, just to get all the angles and shape. Then use that to cut a length of tube, make it about 5% longer than what you think you need
De-bur the tube inner
Next, we start making the flares. You'll need a flaring tool, but not the type found in the hardware, one specifically for double and invert flaring. This is one of mine, nice and fast, easy to use
I modified the tool to ensure the forming clamp comes together flat every time, to be 100% sure that the flares also end up on-centre and square, otherwise they'll leak
I fitted dowels for positive alignment
This is the forming die from the flaring tool, it is probably the heart of it
Clamp up the tube in the forming clamp
With this tool, the forming die is also used for a guage for the length of tube to be left out of the forming clamp.
Fit the forming die
Then the screw press
A few turns (need a few muscles), until the forming die has come down flush with the forming clamp
Then, viola
One double flare.
To do an Invert Flare, 1st make a Double Flare, as above, but leave the tube in the forming clamp. Then using the screw press
A few turns of the handle
And then bingo, an Invert Flare
This is the Bender that I have
I like it because you can get the bends fairly close to the tube nuts (when needed)
And this is a 180 deg bend
Some pipework that I've done recently
