Compression fittings Aluminum only???
Im working on some plumbing using AN fittings and have repeatedly come across where it says For aluminum tubing only when it comes to compression fittings.. I even asked the summit tech dept. and got no answer. I don't understand why you cant use a brass olive on steel or a stainless steel tubing. I did end up using one on my tank to fuel pump line as there is no pressure on the inlet side of the FP. But now Im going from the SS trans cooler line which Im told is a max of 50 PSI. Ideally what I really need is a 1/4" female inverted flare to 6 an fitting. 4,5, an or so would work (I could use reducers to get the 6AN), but after a solid hour on Summits tech support line who could not find my ideal fitting. So This brings me to using either a IFF to hose barb , which I have, or cut off the IF end that came on the cooler lines and use the compression fitting which I also have. Does anybody know why they say tat a compression fitting is to be used on aluminum only, thank you guys for any input. PS I did see a fitting that used a rubber sleeve that goes over the flare or bubble flare on the tube end that is part of a tube to an fitting. cool beans right, but I cant for the life of me find where I saw it last week. Bummer. OK enough of my ramblings, thanks again.

Jim sometimes the best bet is to go to a fleet service dealer as they have all the fittings or find a really good hardware store and not lowes or home despot they only have fans and washer and drier combo's. Besides that they really suck on service. No offense to anyone but that is the way it is with stores like that.

ART , I have to show my ignorance once again but what would I look up to find a fleet service dealer? What type of fleet service, auto, truck?
Ross, OK I see where SS mite not give the needed bite, I thought it might of been the fact that they were two dissimilar metals. And Ill look up Swagelok, I had never heard the name B4, but will do some research.
There is so much I don't know about, and Id be dead in the water with out all you guys. So thank you very much. FTE Rocks on!

10-4 on that Ross. If Im unable to find an all threaded together solution, Ill probably go with the Inverted flare to a hose barb set up. IT wont be visible, (except I will know its there).

Jim in my area we have a shop called Fleet Pride they handle all truck type parts make hydraulic fittings and a lot of tube fittings. Like Ross said swagelok is very expensive and over kill. Go to your local hydraulic fitting house and ask for a catolog of their tube fittings it will have most everything in it plus it is educational and free. Parker, Weatherhead or Gates has them.

Thank you mark, I do still have the 1/4 iff to1/8 npt that I used on the original hard line to radiator conection, and also have the 1/8 to an 6 fitting , however the threads don't match pitch differences. My laptop just crashed, so it may be a week or two to get back to you. .I hate when this happens, I'll try to borrow this tablet again to get back on the board.Thanks again , I know that took a lot of looking, and I really appreciate it. I gotta give back this laptop now. RockOn

Jim, I checked the Aeroquip catalog and found this. I know Gates makes a fitting that is similar. My local auto parts store makes hydraulic hoses and they have the Gates tube to AN fittings. They are used to adapt a hose to a steel line and can also be used to replace a hose on a hose assembly that has a steel tube made as part of the assembly.
The 37 degree JIC fitting shown is the same as an AN fitting, Aeroquip calls them JIC in their catalog. I highlighted the numbers that might work for you.

Well my laptop came on while I was cleaning it up to take in for repair, it acts like a mother board issue. Anyway Im glad I got on the net today, I see you guys are doing a lot of research trying to help me, and I appreciate more than you know. Mark I had been thru all those catalogs but didn't have a clue what the all the things meant. Thank goodness you do. I don't know how long B4 this laptop dies again, so Ill say again thank everybody for your help, I think Ill order the Versa Flare pieces Mark so kindly looked up, and Ill find a way to the site for updates even if its with a magnifying glass and my wife's 5year old cell phone LOL as the laptop is going in for repair.
