I don't know the make-up of the fittings inside, but since you mentioned that you've tightened it with at least temporary success, I gather that it is a hose connection. For what it's worth, in my experience, the hose fittings and their washers are prone to damage from the constant on-off, or from "tightening", and a resultant pooching or gathering. I've found that the application of a silicone lube, such as "Magic Lube" or a similar product sold at Leslies Pool Supply called "Pool and Spa Lubricant" does a great job of facilitating a seal, and also lubricating the gasket to prevent the gathering and pooching, allowing better tightening, thus far fewer hose connection leaks. I also use it an pipe fittings, after the teflon tape, or on any "O"-rings. I keep a tube in my AS toolbox.
