3mm OD x 1mm ID copper tubing?

[Peter Fairbrother]

Anyone know a source? 1/8 x 3/64 would do.


thx

Peter,

    What about this on Amazon
https://www.amazon.co.uk/Copper-Round-Thickness-Straight-Hollow/dp/B0848H9DPW
. How much do you need.

[Richard Smith]

Fine copper alloy tube is used in the oil&gas industry to link gauges
on control consoles to the equipment they are monitoring and
controlling.
Where much of the equipment - wellhead manifolds and the like - are
stainless steel - typically the rarely/never-seen-on-the-high-street
duplex stainless steel.
It's some excellent spec., but one assumes quantity made will give
cost economy(?).

[Peter Fairbrother]

Don't know why I didn't find that, thanks.

Unfortunately the price is a bit high as I was looking for a 30' coil,
not 300mm - but still useful for a trial.

Thanks!

Peter,

    At least it shows it's out there, more digging likely required to
find a source for longer lengths if it ends up being required.

There's a very handy welding/brazing rod available - goes under the
moniker of 'Silbralloy'.

You butt the two ends together, heat to red, apply end of rod, and in a
flash, it runs round and joins copper things. When the joint is cleaned
you can't see the join.

I use it for joining copper water pipe amongst other things: "Look! No
joints!"

Other metals are available.
