The TeeJet GunJet AA23H Spray Gun is a high pressure model capable of handling various spraying applications with pressures ranging from 250-1000 psi. This high pressure spray gun is designed and built so that the inlet body, cap, and spray nozzle are the only parts that come in contact with the chemicals you are spraying. The sturdy design and high-quality materials used, including the stainless steel inlet body and Teflon valve seat, provide long life with the spray gun. The ergonomic design assures positive control and operator comfort, even at maximum flow and maximum pressure conditions. The trigger guard helps prevent accidental discharge for safety, while a trigger lock allows for continuous spraying. This TeeJet GunJet AA23H is available without the extension. If the extension is used, the valve stem will extend through the entire extension length for a drip-free shutoff immediately behind the spray tip. You can use this spray gun with all interchangeable TeeJet spray tips. Does NOT include extension Max. Flow: 5 GPM Max. Pressure: 1000 PSI Max.
