every fitting on my car is compression, as they are trouble free and never defective out of the box. They ARE a little more work initially and aren't as appealing to the ear like nickel plated PTC, BUT I have had more luck with them. I've bought many PTC fittings that either the swivel leaked or were missing the o-ring inside, and when you run everything hidden underneath a car for example, you don't want to find out later when you build air that a fitting is leaking. Obviously, to each their own, but I prefer COMPRESSION.
