  That last post should be 1/8"  copper tubing...

I was looking through my stash for 18" OD copper tube, but I didn't find any.

I figured out that it was not cooper toobing, at least.  Steve

Hello I usually find an old auto-parts store that still stock it for oil and vacuum lines or air-conditioning supplies/repair stores.

The Air Co suckers , now. in Aus. ( bleedy building supplies used to )

A variety of Metric Sizes , had to get 3.3 to get 2 mm bore , relationships uneven bore/ O.D. in range .

Early 1/16 bore - 1/8 O D would lean out anything over or faster than a OS 35 , & maybe That . Good for Vent Pipe tho .
 o.k. on a G-15 going hard on pressure .

SO WATCH THE BORE SIZE , 2 mm min for a big .40  schnurle .

As Matt said some of the auto 1/8" tubing has a thicker wall that restricts the flow just a little and can cause run issues on some engines. I would like to find something like a 9/64" OD with the thicker wall to allow smooth bends. I have found the 1/8" K&S tubing is great for straight run plumbing but kinks (even with a tube bender) for anything over a 30 degree bend. The thick wall stuff can do 90 + in a tube bender without the wall kinking. Any sources?

Best,   DennisT

Gonna bust on Gill here just a bit but actually applies to everyone posting a question for some product or source

We really need to know the desired usage

I can think of all sorts of model usage for 1/8th copper, brass, aluminum tubing but not sure why 36" section would be needed

ID and OD spec needed?
soft, annealed, hard
dead straight or coiled OK

Like a few noted here.... typical copper tubing for hobby use is generally expensive in the K&B pack of 12" length but a Napa or Auto Zone Oil pressure coil is pretty darned cheap per foot

While noting that... you can even price shop across all the auto parts suppliers AND the actual instrument companies Like ISS PRO or Warner..... What I mean is I needed a LONG line from my F350 Tranny to my Oil Temp Gage in the dash

Napa and similar were only 72" long coils for $12.95

Isso Pro web site had a "long reach" 109" coil for $13.48

I love internet searches

I anneal the brass tubing where I want to bend it and it bends just fine
