1/8" copper tubing for TIP

[waldo]

Hey guys,

Want to measure turbine inlet pressure and post exhaust back pressure.

Im sure 1/8" copper tubing with a compression fitting can be made up cheaply, far cheaper than the kits available from autometer.

What type of shop would do this? (Im on the Gold Coast if you know a shop here).

is copper going to be able to withstand exhaust-side temps?

[jeffro ra28]

Could be steel tubing that is copper coated? Besides melting temp of copper is actually quite high at about 1000 C.

You could try your all round ag / fastener shop. Or pirtek?

Compression or flare fitting, which ever is easier
Parts, tubing & fittings of brass or steel oughta be available at any home/building supply or even the worst auto parts.
Steel won't work harden like copper if it vibrates.
If it's permanent, a heat shield will help the gauge.

Dont know what grade copper it is. Just the stuff autometer uses.

I have some on my race car (it came with the car) and that handles red hot exhaust no probs.

Copper is used because of its heat-dissapating properties and obviously handles the high temps.

Thanks for the ideas. Ill start probing around.

another option is to use 3/16 brake tubing. compression fittings to suit are easy to get, and so is the tube. i've used it with much success.

that size of copper should be avalable from a refigeration supplier. I manage a plumbing supplie store but we dont carry that size. where are you located?

[waldo]

Briney - I was thinking that (i once used brake lines as fuel lines too).

riderzx10r - Im located on the gold coast queensland.

if you were in canberra i could sort you out but i have no idea about Fridgy suppliers up there. its a refrigeration size pipe so if you find a shop you will be sweet. yellow pages could be a goer
