Embodiments of the invention provide a bayonet system for attaching a nozzle body to a nozzle turret. The bayonet system can be rotated with respect to a spray nozzle. A seal can be positioned between the spray nozzle and the nozzle turret. The seal can be compressed by moving the bayonet system without exerting any substantial torsion force on the seal. The bayonet system can help prevent unintentional disengagement of the spray nozzle.
