Spray gun attachment for a fluid handling system

A spray gun for fluid supply lines in a fluid handling system, the spray gun comprising:

• an elongated gun body having an open inlet end portion and an open outlet end portion and an open fluid pathway extending between the inlet end portion and outlet end portion;
• a swivel connector including:
• a rotor having an open first end portion, an open second end portion and an open fluid pathway extending between the first and second end portions;
• a housing stem having an open first end portion, an open second end portion, and a fluid pathway extending between the first and second end portions;
• the first end portion of the housing stem being in open fluid communication with the second end portion of the rotor, whereby the open fluid pathway of the rotor is in open fluid communication with the housing;
• a bearing cup having an open housing stem end portion, an open rotor end portion, and an open interior portion;
• the rotor end portion of the bearing cup being operatively coupled with an exterior surface of the rotor between the first and second end portions of the rotor;
• the housing stem end portion of the bearing cup being operatively coupled with an exterior surface of the housing stem between the first and second end portions of the housing stem;
• and
• a bearing assembly having a bearing raceway with surfaces that are at least partially defined by flat surfaces on each of:
• a bearing channel;
• a bearing wall;
• and an interior bearing wall within the interior portion of the bearing cup;
• the bearing channel formed to have a V-shape, having flat opposing first and second walls;
• the bearing wall and the interior bearing wall within the interior portion of the bearing cup are flat, opposing surfaces that together generally define a V-shape that is open toward an open end portion of the bearing channel;
• the second end portion of the rotor being operatively coupled with the inlet end portion of the gun body, whereby the open fluid pathway of the rotor is in open fluid communication with the open fluid pathway of the gun body, and the rotor and gun body may together freely rotate with respect to the housing stem.
