Part 13403 is a replacement inlet valve holder for compatible SprayTech airless sprayers. This component secures the inlet valve assembly within the pump, ensuring proper alignment and sealing. When the original holder becomes worn, corroded, or damaged, replacement restores proper valve function and prevents fluid leaks.

The 13403 inlet valve holder is a direct replacement component for SprayTech Airless EP2300 SE, EP2300, and EP2400 sprayers. This precision component is installed in the pump fluid section, where it secures and positions the inlet valve assembly. The inlet valve holder maintains proper alignment of the valve seat, ball, and stop, ensuring reliable one-way flow of material into the pump chamber. A correctly positioned inlet valve is essential for maintaining prime, achieving rated flow, and preventing material backflow. A worn, corroded, or damaged holder can allow the valve components to shift or misalign, causing loss of prime, reduced output, spitting, and pressure fluctuations. It may also lead to fluid leaks past the valve assembly. This replacement holder is manufactured to exact specifications for proper fit and sealing. The material is selected for compatibility with paints and solvents. Installation requires careful cleaning of the pump cavity and proper seating of the valve components. Regular inspection during pump service helps identify holder damage before it affects performance.
