-8 AN fitting threads into -10 AN or 7/8-14 O-ring port on cooler core to attach transmission or oil lines.


Had to order the Derale 8 AN fittings to properly install a Derale Transmission Cooler. The 8 AN fittings allowed the OE hoses on my Ford E-450 to slip right on with no modifications. Excellant product with proper fit/finish one would expect from Derale.
