A fluid coupling device employs a male spherical member with a fluid receiving bore and a female housing. The spherical member abuts two axially spaced Teflon ring seats between the member and the housing in the housing chamber. The ring seats reduce friction between the member and the housing and axially retain the member in the housing with no metal to metal contact. A first O-ring provides fluid sealing between the spherical member and housing inner wall in the chamber. A hose receiving nipple member with a fluid receiving bore has a threaded concave end with a peripheral region that engages the first O-ring to hold the O-ring against the spherical member, one of the ring seats and housing chamber wall to seal the interface between the spherical member and housing. The nipple member has a flange which abuts the housing to limit squeezing action on the O-ring to ensure sufficient contact of the O-ring and mating surfaces to obtain a good seal without creating excessive friction loads. A second O-ring seals the interface between the flange and housing.
