A "3/8" FNPT Inlet Spray Gun Trigger 1/4" FNPT Outlet 10.5 GPM @ 4500 PSI" is a specific type of spray gun designed for hydro excavation equipment. Let's break down its features and specifications:

Key Features:

  1. Inlet Size: The spray gun has a 3/8" FNPT (Female National Pipe Thread) inlet. This is the connection point where the pressurized water or fluid enters the gun.

  2. Straight Spray Gun: The "straight" design means that the spray gun has a linear shape, which allows for precise control and targeting of the water or fluid stream.

  3. Trigger Mechanism: It is equipped with a trigger mechanism, which can be squeezed to release the pressurized water or fluid and released to stop the flow. This allows for on-demand control of the spray.

  4. Outlet Size: The spray gun has a 1/4" FNPT (Female National Pipe Thread) outlet, which is where the water or fluid exits the gun.

  5. Flow Rate: The gun is rated for a flow rate of 10.5 gallons per minute (GPM). This indicates the maximum volume of water or fluid it can handle per minute.

  6. Pressure Rating: The gun is designed to handle high pressure and is rated for up to 4500 pounds per square inch (PSI). This high-pressure rating is important for hydro excavation applications, which require powerful water jets to break up and excavate soil.


A spray gun with these specifications is commonly used in hydro excavation equipment for various applications:

  1. Hydro Excavation: Hydro excavation is a non-destructive digging method that uses pressurized water to break up soil and a vacuum system to remove the resulting slurry of soil, water, and debris. The high flow rate and pressure of this spray gun are essential for effective soil removal.

  2. Precision Excavation: The straight spray gun design allows for precise targeting and excavation around underground utilities, pipelines, and other sensitive structures without causing damage.

  3. Utility Locating: Hydro excavation is used for exposing and locating underground utilities and infrastructure, making this spray gun ideal for these tasks.

  4. Construction and Trenching: It is used for trenching operations, such as digging trenches for cable or pipe installation.

  5. Cleaning and Surface Preparation: In some cases, this spray gun can also be used for high-pressure cleaning and surface preparation.

The combination of a high flow rate, high pressure rating, and trigger mechanism makes this spray gun a valuable tool in hydro excavation operations, where precision, control, and power are necessary to safely and efficiently expose underground utilities and excavate soil without causing damage.
