Thread: cooler line adapters for tranny cooler.

I'm installing a tranny cooler. My issue is getting some barbed adapters so I can run inline with the stock cooler. I want to run a barb off the stock cooler outlet, to the new cooler, then back into the stock line. It looks as if I need to run 5/16 adapters...but I can't find any. 3/8 is to big and 1/4 is to small, has anyone gotten around this? Or am I looking for the wrong kind of adapter?

I've taken pieces of the original lines, cut and put a slight bubble on the end of them. Never looked for barbs, just tossing out another idea.

I've thought of that, I'd prefer barbs if anyone had found some that worked.

Just getting back around to this. Are the fittings -AN?

I use 3/8 barbed fittings from Autozone the ones for the air tools
