Question:
Wonder if you could advise the correct cooler line fitting I need... Brand new Champion rad. They told me fitting bore is 1/4 27 NPT. The other end to tranny seems to be the same thread size but is a flare end. Do you have this fitting? 73 F100 360 THANKS!!

Expert Reply:
In the realm of 1/4 inch fittings, we have a few parts. We have the Derale 1/4 inch NPT Female x 3/8 inch Barb Straight Hose Fitting, # D98104.
There is also the Derale 1/4 inch NPT Male x 3/8 inch Barb Straight Hose Fitting, # D98100.
Finally, there is a set, Derale Radiator Adapter Fittings, # D13014, which comes with a 1/4 inch NPT male and female fittings and a 3/8 inch NPT male fitting.
I was unable to find anything that was specifically listed as a 1/4 inch -27.
All of the transmission cooler kits listed for your truck show only the Insta-dapt Radiator Adapter, # D13004, and either 11/32 inch hose barb inlets or 1/2 inch NPT x 3/8 inch hose barb fittings.
