An air cap arrangement for a spray gun, said air cap arrangement comprising:
- an air cap;
- an air cap ring;
- and
- a retaining ring,
- wherein the air cap has a circumferential outer surface extending longitudinally, and the air cap ring has a circumferential inner surface extending longitudinally,
- the air cap ring comprises a groove configured to extend on the circumferential inner surface of the air cap ring,
- the air cap comprises a groove configured to extend on the circumferential outer surface of the air cap,
- the retaining ring is arranged in the groove of the air cap ring and the groove of the air cap to limit the axial movement of the air cap within the air cap ring,
- the air cap ring further comprises a protrusion configured to protrude radially from the circumferential inner surface of the air cap ring,
- the groove of the air cap ring is further configured to extend circumferentially and to be located closer to a front end of the air cap ring than the protrusion,
- the air cap further comprises a step configured to protrude radially from the circumferential outer surface of the air cap,
- the groove of the air cap is further configured to extend circumferentially and to be located closer to a front end of the air cap than the step, and
- a front face of the step, which faces the front end of the air cap, is configured to contact against a rear face of the protrusion, which faces a rear end of the air cap ring, when the air cap arrangement is assembled.
