The S-series (prefix \"S\") has a larger internal bore for higher air flow, making it better for tools with greater CFM demand such as impact wrenches, die grinders, and sanders. Check your tool's CFM rating: if it exceeds roughly 5 CFM at 90 PSI, the S-series is the safer choice.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eWill a P-series plug connect to an S-series socket?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eNo. P-series plugs are only compatible with P-series sockets, and S-series plugs mate only with S-series sockets.
