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 ________________________________ Message 2 _____________________________________ Time: 02:08:44 PM PST US From: doug sapp Subject: Re: Yak-List: longest pneumatic line 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.

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 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.

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!
