I was going to warn you but I guess too late. AA is the McMaster-Carr of aero fluid fittings - they sell to just about everyone who flys fittings professionally. If you need something that is not very common, you're better off making your own usually. For Ed, a 1/4" NPT fitting has quite a bit of meat in it, I would think you would have enough room to get a check valve in it. I've drilled out -4 fittings for 1/4-28 set-screw orfices, which is a pretty handy trick. -RM On Mon, Oct 14, 2013 at 2:33 PM, Ed Kelleher <Pres@xxxxxxxxxxxxxxxxxxxxx>wrote: > Ditto Lloyd, great catalog and they even have weights! > > Got right through to one of their engineers. > > They have a flared tube to blank end, with a through hole the size of the > AN hole, about .172" for a -4. > AAB1038-4 A (Aluminum) > > Minimum order of $100. > > They had four they'd let me have ... for $30 each. :-) > > Didn't think I said Boeing or Lockheed when I called. > > Anyway, good stuff.
