Definition:
A FLUID LINE FITTING HAVING A PIPE, TUBE OR HOSE CONNECTION OR A THROUGH HOLE TO ACCOMMODATE A BOLT, FLUID PASSAGE ON ONE END. THE OTHER END MUST HAVE AN EXTERNAL OR INTERNAL THREAD FOR CONNECTING A MATING PART TO FORM A SELF-SEALING COUPLING ASSEMBLY. THE FITTING HAS EITHER A SELF-SEALING FEATURE FOR THE PURPOSE OF AUTOMATICALLY SHUTTING OFF THE FLOW OF FLUID WHEN DISCONNECTED FROM ITS MATING HALF, OR, IF IT HAS NO SELF-SEALING FEATURE, IS SPECIFICALLY DESIGNED TO MATE WITH A FITTING WITH A SELF-SEALING FEATURE. FOR SELF-SEALING FITTINGS WITH A QUICK DISCONNECT END, SEE COUPLING HALF, QUICK DISCONNECT. FOR FLUID LINE FITTINGS WITHOUT A SELF-SEALING FEATURE, SEE COUPLING (AS MODIFIED).
