pipe join

Post by barry badger » Mon Jul 01, 2019 10:44 pm

Does anyone have any experience/opinion of joining bx metal hydraulic pipes? there's a shop on ebay selling copper nickel pipe with connectors for splicing in new sections of pipe. I'm currently carrying out much welding on my txd for its mot and noticed one of the front to rear pipes has been rubbing on the rear subframe quite badly and needs replacing. I was looking for copper pipe on ebay and came across this repair option.

Not something I would recommend, it's just as easy to replace the complete pipe for what they cost
Pleaides in Sawtry can supply the pipes to length and ready to fit.

I think it depends on the type of connector as it has to withstand the huge pressure in the pipe.
I bought a 3.5mm compression connector some years ago but have never had the nerve to fit it anywhere yet. Although I would not rule it out for the front to rear metal return pipe if that got damaged. But it is better to play safe really.

If you mean the compression type that uses a steel cutting ring / olive we used to use them all the time when I was a Plant Machinery fitter on hydraulic plant when steel pipes got damaged on excavators without issue. I've never used any as small as Citroen feed pipes though.

There used to be a kit you could buy for a buy the side of the road repair which was a flare tool for Citroen hydraulic flare and a union piece. Cut a section of bad pipe out, flare either side, screw back together.

Thing is, in my experience, when you fix one hole another soon finds its way out. I understand this has been a chaffing issue, but still, do you want to do the job twice?

Pleiades will sell you a pre-flared cupronickel pipe of the right length for not a lot of money. Might be worth taking the plunge? Cupronickel is a far better solution for our hydraulics and much more flexible than the original pipe. It doesn't give quite as neat of a run as the original pipes, but will likely outlast the car!
