Hi Jon;
Sorry for the delay. Just found your last two posts in my junk file.
Happens all the time but I forget to check it!
If I had read all of your first post (re: container) I would not have
suggested cutting it so I=99m sure you ignored that nonsense.
There is some 8 mm tubing probably also 1 mm wall (though possibly 1.25)
It can be easily replaced with AN Std. 5/16 tube but if the price is
right might as well get some.
Best;
Walt

This is the 4mm ID, 1mm wall, 6mm OD stuff in the CJ, but it will be
from Poland not China. They use exactly the same on the Polish
helicopters.
Is there another size tubing I should ask him to put in as well?

Hi Warren;
That is actually a pretty fair price for 1/4" X 0.049" 5052!
The standard and most used 1/4" X 0.035" (while a whole lot cheaper)
actually does not meet the strength requirements of the stock 6mm X 1mm
CJ
tubing. Assuming of course that the material spec. is equivalent and I
have
no reason to believe otherwise.
I used to maintain a stock of 1/4" X 0.049" for a batch of Harvards &
T6's.
Required for the 1200 psi hydraulic system. Sometimes had a hard time
finding it!
Cheers;
Walt

Jon,
Aircraft Spruce has exceptionally high quality =C2=BC inch 5052-0
aluminum tubing
that is almost as stiff as stainless steel.
Here are the numbers:
OD: 0.250
ID: 0.152
Thickness: 0.049
Length: Comes is 6 ft. sections, but will ship this in 12 ft. sections
if
you want.
Part Number: 03-39250-12
Price: $28.80 for 6 ft.
$57.60 for 12 feet.
Web: https://www.aircraftspruce.com/catalog/mepages/alumtube_5052.php
The advantage of using =C2=BC tubing is that 37=C2=B0 flaring tools are
readily
available. Imperial stopped making a 37=C2=B0 flaring tool for 6 mm
tubing a few
years back.
Hope this helps.
