i will have a look in the morning to see what size the aluminium tube is we use,hopefully there is some in the shed,but i don't know what pressure it is rated at.
Ahhh. The P38A EAS line runs at up to 160psi so it could have been OK. The P38A air lines use push-in fittings like those pictured. You might be able to adapt some.Quote:

use 1/4 copper and a brake double flaring tool only use the first flare, seal the thread and back of the flare with loctite 567 and let is stand for at least 24 hours to set up.
common as.
The burst pressure of Nylon tube drops significantly as the temperature rises plus the seal in a pneumatic fitting would typically only be rated to 60C.Quote:

Aluminium would have been used for low cost (and heat dissipation), steel or copper could be used as a replacement. Copper easier to flare.

The aluminium tube I have here is 6.3mm,so 1/4 inch.
Have seen 6 mm copper tube,Stubbs on some of our compressers made in Europe are 6mm,but never seen it anywhere else.Wont be available in Australia.
I would try 1/4 copper first and see how you go.
Any AC or Refrig mechanic would have a piece or a gas fitter.
Hi, thanks for all the help so far. Flanged the tube and it seems the be holding 8bar just fine. Not sure how long the tube will hold though... would prefer the alloy tube later on.https://uploads.tapatalk-cdn.com/202...94ff51ce77.jpg
Let us know how the nylon goes, I’m sure the heat will be the killer???Quote:

I think I drilled the flare nuts out with a 1/4” bit??? Maybe 7mm???
I assembled it about 5 years ago and it’s survived the “farm service trailer” flogging [emoji12]
(Even the old Thumper compressor has survived)
