    Won't be long before I need to mount new copper brake lines to my chassis. The plastic OEM clips won't as my plumbing has been altered from original.

    So these are the standard method, will do the trick if I can't find anything nicer which would also hold both my brake lines with one clamp.

    These are much neater, will hold both my brake lines. But no rubber mount which is apparently important on copper lines to reduce work hardening.

    These fit the bill but no way at £20 a part:

    Also need some way to mount my fuel lines, which now run in plastic, and the thick cables that supply power to my winch. This seems easiest solution, but something more solid would be nice:

    You might want to check the use of copper

    I agree with the above, use kunifer rather than copper. My 34 car had copper as original pipework & restored it using 1/4” kunifer, far superior material & just as long lasting.
    I used black nylon p clips & some of the original spring pipe clips to secure it to the chassis.

    I used nylon p clips. If two lines close together i just staggered the clips slightly.

    My long clips for fuel lined too as they come in all sizes. Very quick to drill and pop rivet on.

    I usually use hellermann cable tie saddles fastened to the steel with pop rivets then cables/ pipes are easy to remove and replace.
    In my mind the old p clips look a bit unsightly nowadays.

    But have recently bought these to try [​IMG]with the idea of saving pop rivets and the inevitable corrosion, pulling them through the steel till the plastic washer appears then cut off the excess, if used through very thin steel you could use stainless washers to space and fill the gap either top or bottom whatever suits

    Hello all,

    I asked the Automec rep (Automec sell both pure copper and Kunifer) if Kunifer was better than copper. He said their copper lines are as good as Kunifer and it is a personal choice. The copper lines they sell are thick walled.
    I used the rubber lined 'P' clips on my car, by the way.

    Not sure "treated copper" is the right description for kunifer, it's actually an alloy that includes copper and nickel

    Copper, iron and nickel IIRC.
     
  13. Methinks he speaks with forked tongue! Copper work hardens when unsupported. Kunifer is recommended for brake line because of that. I wouldn't want to risk it, thick walled or not. How do you get the unions over thick walled tube anyway?

    Actual comparison between brazed steel, copper & kunifer tubing.

    Ah it's that copper+nickel mix, yup, that's what I meant when I said copper, I meant certified copper alloy. I know not to use pure copper.

    I ended up tigging M5 bolts under my car (nut head to floorpan) and using nylon P clips

    with the P clips you can use 2 with one fixing

    I did, but still wanted to ask the question as I'm sure I'd seen cable ties failing an MOT on a TV programme.
