| Subject: | longest pneumatic line |
I have a chance to get some original pneumatic tubing into a container comi
ng from Poland.
The guy is going to send straight pieces and wants to know how long... I to
ld him at least two pieces 4 meters long. Should I tell him 5? Anybody ha
ve a feel for what the longest run of tubing is in the CJ? I want to just
have stock for the future so there's not something specific I'm fixing now.

Jon,
A 12 foot long package is going to cost a bundle by the time you get it, as
most shippers charge "over length" when packages exceed 8 feet. Best to
have him coil it in 3 foot square box if you need 12 feet.

Jon,
Aircraft Spruce has exceptionally high quality 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 tubing is that 37 flaring tools are readily available.
Imperial stopped making a 37 flaring tool for 6 mm tubing a few years back.
Hope this helps.

I have had them replaced on the Housai. They fit fine. As Im sure you know its
not an easy job. I dont know how you do it without loosening all the jugs.

Jon;
I don=99t know off hand what the longest line is in the CJ but, as Do
ug noted, shipping 4 m (12.5 ft.) lengths will be very costly. I would thi
nk cutting in half would cover for most of the CJ.
Is this the standard 6mm X 1mm tubing ? If so I would not recommend attem
pting to coil it for shipping. This is a high quality tubing which I belie
ve is a direct equivalent to our 5052 =9CO=9D cond. standard.
It is not amenable to coiling!
The junk you can buy in a coil is thin wall 3000 series alum and is not acc
eptable for use in any pressurized aircraft system.

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

This is the 4mm ID, 1mm wall, 6mm OD stuff in the CJ, but it will be from P
oland 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?
