What cooler are you using? I purchased a tiny derale tube and fin but couldnt find anywhere i liked so i didnt use it. It has -6 male flares on it and you can have it for shipping if it works for you.What's your hose rated to?
I could do that for the discharge side of the york and remove the barbed brass nipple, but I still would need something to connect onto the barb of the cooler hence why Im using hose clamps.
