1/2" to 1/4" Brass Hose Reducer Coupler - 2pcs for Water & Air Tubing

These are perfect for my transmission cooler install. For some reason ford uses 1/2" cooler lines and the trans cooler was 3/8". These barbs really bite into the hose and make a good seal unlike some cheap brass barbs I've used in the past. It also makes it a pain to remove. I double clamped the hose onto the barbs and haven't had any leaks from these barbs. They're also a good deal.
