Zoomup's pipes

I had wondered about the flare at the end of the tubes, but this is one that I have not seen before, including the O-rings. If new tube nuts were made: (1) how would the new flare be made; and (2) how would the new pipes be joined to the old?

Basic pipe flaring made simple.....

Z,

yep that is the sort of thing you would need to acquire or make for the right pipe size, but in a typical flare plumbing fitting, small errors in the pipe profile are corrected - squeezed out of it - by the compression of the fitting as the tube is trapped between 2 bits of metal. Here you seem to have a rubber or nitryl O-ring, bearing on one side of the flare, so it will not provide the force to correct any error in the trumpet angles, and will leak.

However this is conjecture - a description of which surfaces form the high pressure seal(s) would help. and ideally a dimensioned drawing will reveal all.

That's not quite how I would flare brake or fuel pipes, or even a power steering pipe.

Please may we see a picture of the holes into which the pipes are inserted? Useful also to know what is on the other end of the pipes (or do you just want to bypass the cooler?) and something about the vehicle.
