The Graco 289771 is an AirPro HVLP air cap kit used as a repair and replacement part for compatible Graco AirPro HVLP air spray guns. It should be described as an air cap kit or spray gun repair part, not as a diaphragm pump, complete spray gun, spray nozzle, or pump assembly.

This air cap kit is designed for AirPro HVLP guns using 0.040-0.070 inch / 1.0-1.8mm nozzle sizes. The air cap plays an important role in spray atomization, spray pattern formation, coating transfer efficiency, and finishing quality. When the original air cap is worn, blocked, damaged, or contaminated, replacing it with the correct air cap kit can help restore stable spray performance.

The Graco 289771 air cap kit is commonly used in industrial finishing, automotive coating, metal parts spraying, furniture finishing, plastic parts coating, equipment repainting, maintenance workshops, and production line spray systems. It is suitable for repair teams and maintenance departments that need to keep AirPro HVLP spray guns working reliably.

For replacement applications, the complete part number 289771 must be checked carefully. Similar Graco AirPro air caps may look alike but can differ by spray technology, nozzle size range, spray pattern, gun type, and application material. Please do not replace an air cap only by appearance. The gun model, nozzle size, needle size, air cap number, and coating application should be confirmed before ordering.

Before ordering, please confirm the original spray gun model, old air cap part number, nozzle size, needle size, spray technology, material type, and required spray pattern. Clear photos of the gun label, old air cap marking, nozzle, needle, and spray gun front assembly can help confirm compatibility and reduce replacement risk.
