Go to any auto parts or big box hardware store & they should be able to help you in the air tool section. Campbell Hausfeld usually packages some air compressor accesories together.
I'm not sure what the quick connect fitting style (SAE I think) is, but it is the most common style. The reason I mention this, is the local garage uses a different style than our shop tools. If we borrow tools from them, we have to change the male fitting on the tool, before we can connect it to the hose.
