Titan part 773-172 is a flex tube (cut to length) designed for use on HVLP AirSpray ProFinish TS40, TS50, and HVLP AirSpray Quart Cup systems. This flexible tubing connects the fluid cup or container to the spray gun, allowing material to flow smoothly under gravity or low pressure. Replacing a cracked, kinked, or hardened flex tube restores proper material delivery, prevents air leaks, and ensures consistent spray performance.

The Titan 773-172 Flex Tube is a genuine OEM replacement tube designed for HVLP AirSpray ProFinish TS40, TS50, and HVLP AirSpray Quart Cup systems. This flexible tubing connects the fluid cup to the spray gun, allowing coating material to flow by gravity or low‑pressure siphon action. Supplied as a cut‑to‑length piece, it can be trimmed to the exact size needed for your specific setup.
Over time, flex tubes can become hardened, cracked, or kinked due to exposure to solvents, age, or repeated flexing. A damaged tube can cause material starvation, air leaks, inconsistent flow, and poor atomization. Replacing with the correct 773‑172 flex tube restores proper fluid delivery, eliminates leaks, and ensures a smooth, even spray pattern.
