studeboy Posted November 23, 2014 Share Posted November 23, 2014 I am attaching a picture of what I think is a type of compression fitting used on the copper gas line of my 1922 car. I am building a new gas line and would like to find matching fittings. Also any advise on how to install. I am familiar with flared fittings and have made lots of those but not this type of fitting.

1939_Buick Posted November 23, 2014 Share Posted November 23, 2014 (edited) Looks to be an olive compression type that goes over the tube. Using your existing nut will the issue. What thread is it? Is the olive part of yours metal? Can you heat the copper tube to get it off?https://www.google.co.nz/search?q=olive+tube+fitting&client=firefox-a&hs=113&rls=org.mozilla:en-GB:official&channel=sb&tbm=isch&tbo=u&source=univ&sa=X&ei=FEVxVIWHK8SxmAXwxIGYBg&ved=0CFUQsAQ&biw=1366&bih=610 http://www.legris.com/Legris_ecom/RechercherSousFamillesFamille.do?codeActivite=BP&codeGroupe=01&codeFamille=01&codeFiliale=export&codeLangue=en_GB Edited November 23, 2014 by 1939_buick (see edit history) Link to comment Share on other sites More sharing options...
Guest buickkuhn Posted November 23, 2014 Share Posted November 23, 2014 On my 41 buick I cut the line near the fitting and drilled the tube out of it "carefully" , then reused the fitting flare part on new pipe then a small phillips screw driver to make the reverse flare part . This is the kicker , I had to use refrigerant copper line to have the OD to be proper . The standard line is made thinner than back then - and yours is even older . Calipers and time are your best friends . Have fun mine worked Link to comment Share on other sites More sharing options...
