Sharkbite (Home Depot), Gaterbite (Lowes), Watts and Seatech (various hardware/home improvement stores) all have similar no tools needed push on fittings, and they all work quite well for RV use. My standard spares include a couple of elbows and a couple of in-line shut-off valves. The valves can be used as connectors or end caps, and of course as shut offs until a proper repair can be made.
