Titan part 773-173 is a screen (filter strainer) designed for use on HVLP AirSpray ProFinish TS40, TS50, and AirSpray Quart Cup systems. This fine-mesh screen filters coating material before it enters the spray gun, preventing tip clogs and ensuring a smooth finish. Replacing a clogged or damaged screen restores proper flow, improves atomization, and reduces downtime caused by tip blockages.

The Titan 773-173 Screen is a genuine OEM replacement filter strainer designed for HVLP AirSpray ProFinish TS40, TS50, and HVLP AirSpray Quart Cup systems. Installed in the fluid path, it captures debris, dried paint particles, and other contaminants before they reach the spray tip. This fine‑mesh screen is essential for preventing tip clogs, maintaining consistent atomization, and achieving a professional‑quality finish.
Over time, the screen can become clogged with dried material or torn from cleaning. A restricted screen reduces material flow, causing spitting, poor atomization, and uneven spray patterns. Replacing with the correct 773‑173 screen restores proper filtration, ensures smooth material delivery, and minimizes downtime caused by tip blockages.
