andym Posted September 16, 2015 Share Posted September 16, 2015 Can anyone help identify this fitting, used for charging the Abbot equilibrator with air? It seems to have a 1/2" UNC thread but no-one I've tried has seen anything like it. Andy Quote Link to comment Share on other sites More sharing options...
robin craig Posted September 16, 2015 Share Posted September 16, 2015 Have you thought to unscrew it and look at the other end to see if that is something more normal? That might be a devilish way to creep up on the problem and win! R Quote Link to comment Share on other sites More sharing options...
andym Posted September 16, 2015 Author Share Posted September 16, 2015 (edited) Being devilishly sneaky I've already done that, Robin - it contains a non-return valve with a UNF thread on the other end: The entire assembly was manufactured by Ermeto, who have confirmed the 1/2" UNC thread but they don't know what it's designed to fit either!

cosrec Posted September 17, 2015 Share Posted September 17, 2015 the lock wire holes make the fittings look like aircraft types although never having worked on aircraft I cant be sure. Martian power steering pump had similar fittings and sure that pump was areo industry Quote Link to comment Share on other sites More sharing options...
fesm_ndt Posted September 17, 2015 Share Posted September 17, 2015 is that the type of fitting you unwind a quarter turn, to fill and once full tighten it back up? Aircraft struts used to use this type I mention Quote Link to comment Share on other sites More sharing options...
