My O-360's first life was in an Enstrom helicopter, HO-360XXX with the single "dual" bendix mag. The current fitting pictured above is AN815-10D, With a 5/8 thread. I haven't found a fitting with 5/8 thread to 8 flare and a 90. I tried a AN912 but I have only found 3/4 and 1/2 to 3/8 flare. Last option would be to see if a 90 on my hose would fit.
"The fitting above "can" be used, providing the case has been tapped for a straight thread. In that instance, an appropriate O-ring must be placed it the non-threaded crook between the threads and the hex section to accomplish a seal. More info needed to give informed advice."
Charlie, you are correct! The union fitting does have the O-ring and must be straight threads tapped into my accessory case. Are there any reducers/adapters (straight thread with O-ring - 3/8 NPT) for this?
Perhaps find a plug to fit my accessory case then drill and tap for 3/8 NPT?
Ah, that is the fitting I currently (not in purple, my daughter would like it)have but I need a 90. I'll check out jegs!
Thanks!
Think I finally found it, for $32.95!! 90 degree AN8 to male 7/8-14 straight o-ring boss fitting.
