The Rapid Air system is top notch for me. The O-ring style fittings are well designed and pretty robust, ZERO leakage is easy. And everything is so easy to change and reconfigure if you decide to. I direct buried a 3/4" RA line from my house to my new shop about 150+ feet away so all my house airlines would stay hot when I move my compressor from the garage to the new shop. I searched on Ebay and found a seller in Lincoln NE that had great prices and when I called them to ask a few questions they actually knew something. Ha I have picked up a few fittings at our Northern Tool Store, but I didn't realize Lowes carried RA, thanks for that. Good Luck
