Larger Hose Fittings for Derale # D13611 on 2010 Mercury Mariner

Question:

Hi just did an install on a 2010 Mercury Mariner v6 4x4 same as an escape Had an issue with the hose not fitting over the factory trans line both locations, at the radiator and at the line going back to the transmission the hose that come with this is 3/8 hose my question is do they make different barb Fittings that go into the cooler? Like a large one that will work with the larger hose that the factory line are? I was able to force it over the factory lines and used two camps to make sure it does not come off,but would prefer a different screw in bard line that matches the size of the factory lines and hose making this an easier set up. I do know this is not made for one type of car or truck but was wondering if they make different barb Fittings than what come with it.

On the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets - Class I -Extra Efficient # D13611, the fittings that come with the unit are 1/2" NPT x 3/8" hose barb.

The other option for fittings are the Derale 1/2" NPT Male x 1/2" Barb Straight Hose Fitting - 2 Piece # D15712 along with the 1/2 inch inner diameter hose # D15700 and hose clamps # D13008. This slightly larger size is the only other option for the 1/2" NPT fitting on your cooler.
