A fluid delivery assembly for an infusion device is disclosed herein. The fluid delivery assembly includes a body section having a fluid chamber, a fitting section extending from the body section, and a plug component. The fitting section has a sidewall structure with a through-hole formed therein. The sidewall structure at least partially defines a cavity. The plug component is rotatably coupled to the fitting section. The plug component includes a lower section located in the cavity, an actuator to facilitate rotation of the plug component, and a fluid flow path defined in the lower section. The fluid flow path has an outlet opening and a chamber opening fluidly coupled to the fluid chamber. The sidewall structure blocks the outlet opening when the plug component is in a closed position. The outlet opening is fluidly coupled to the through-hole when the plug component is in an open position.
