Fna Group 80178 Pressure Washer Spray Gun 5075 Psi

Product Description

The FNA GROUP 80178 is a professional-grade pressure washer spray gun rated for commercial and residential pressure washing applications. It handles up to 5075 psi and 12.0 GPM, making it suitable for high-demand cleaning tasks on industrial equipment, walls, floors, and vehicles. The gun is compatible with both hot and cold water machines and is rated up to 212 degrees F. It features a 3/8-inch FNPT inlet and a 1/4-inch FNPT outlet, and ships with M22 and Quick Connect (QC) adapters for broad hose and wand compatibility. Licensed contractors and experienced equipment operators are the primary installers of this component.

The 80178 is designed for use across commercial job sites and residential settings where a durable, high-flow spray gun is needed. It serves as a direct replacement or performance upgrade for most existing pressure washer spray guns rated within its psi and GPM range. Typical applications include surface preparation, fleet washing, building exterior cleaning, and equipment degreasing. Because it works with hot or cold water supply, it fits into a wide range of pressure washing system configurations without additional modification.

Installation Notes

Installation is typically performed by pressure washing equipment technicians or qualified service professionals. Relieve all system pressure and shut off the pressure washer before disconnecting or connecting any spray gun. Confirm inlet and outlet thread compatibility before attaching hoses and wands, and hand-tighten connections before applying tool torque to avoid cross-threading. Always engage the trigger safety lockout when the gun is not actively in use.
