BG, I really like the idea of the Push to Connect fittings but they occasionally have let me down too. I suspect the compression nut and ferrule probably makes a more secure fitting, but they are so dang difficult to work with in comparison. I've noticed that this Winter, with its' below average temperatures, my air compressor took some time to pressure up to activate the exhaust brake. Of course once it had a chance to warm up everything was fine. I am hoping that this was temperature related and not a sign my compressor is getting ready to give up the ghost. I have the BD exhaust brake and to do a compressor change-out under the wheel-well is considered a first-class aggravation by my wife, LOL. I think if the compressor takes a crap, I'm going to install a five-gallon tank and 100%-duty compressor and get those air horns I've always wanted, as well as have plenty of onboard air for the exhaust brake, and airing up the tires on my truck and camper.
