Abstract
Fluid couplings can be designed to prevent spillage of fluid when disconnecting the couplings after use. In some embodiments, the fluid couplings include internal valve components but no springs, or no springs in the fluid flow path. In some embodiments, the internal valve components of a male coupling and a female coupling can be designed to latch together in an abutted arrangement.
