Compressors

Straight, fat hoses may be cumbersome to coil, but they deliver more air and are better behaved than "Slinky-style" recoild hoses, which lose pressure, especially over distances of 25 feet or more. Both types of hoses use the universal "quick-connect" couplings that plug into the tools and compressors. Recoil models require you to screw on the couplings, so they're more likely to leak than the built-in couplings on straight hoses. Wrap Teflon tape around the fittings' threads if you feel air escaping.
